After using Postinor, when does your period begin? Why does bleeding occur after postinor and is this normal?

Many women face the problem of severe bleeding after postinoration. Although this side effect makes women worry, fortunately, it is not always a sign of health problems.

Postinor is a contraceptive that is not intended to routinely prevent unwanted pregnancy. It can prevent pregnancy if taken within seventy-two hours of unprotected sex. Scientists estimate that postinor generally prevents pregnancy in 80% of cases. If you take the drug on the first day after intercourse, the probability that pregnancy will not occur is 95%. On the third day, its effectiveness decreases to 58%. Although this contraceptive is very effective, it can cause some serious side effects.

Bleeding after postinoration: when to worry

The first menstrual bleeding after taking Postinor is often heavier than usual - this is a fairly common occurrence. The average volume of discharge during a woman's period is 30-35 ml, but any volume in the range from 10 to 80 ml is considered normal. Women who are tall, have given birth, or are going through perimenopause tend to have more than average menstrual bleeding. One of the reasons for excessive heavy bleeding, the volume of which exceeds 80 ml, is a hormonal imbalance. Postinor can cause a temporary imbalance of hormones, which leads to very heavy menstrual bleeding. In most cases, this is not something to worry about. You just need to always have a sufficient number of pads or tampons on hand and change them more often than you usually do. For maximum protection, you can use pads and tampons together. As a rule, after a month, menstrual bleeding returns to normal.

However, in the following cases, you should consult a doctor as soon as possible:

You are bleeding so heavily that you have to change pads at least once an hour for hours on end. If this bleeding continues for twelve hours or more, call an ambulance.
You have to change pads in the middle of the night.
There is blood with clots for more than one day.
Due to heavy bleeding, you had to give up some activities, such as working out.
You have signs of anemia, such as lethargy, weakness, shortness of breath.

An important indicator is how long the bleeding lasts after postinoration. Often, menstruation lasts one or two days longer than usual after taking this drug. Sometimes they can even last seven or eight days. If after the fourth or fifth day the bleeding becomes light and not causing discomfort, you are probably fine and will stop completely after a few more days. If you continue to experience heavy bleeding for six to seven days, you should definitely seek medical help. If bleeding lasts more than ten days, you should go to the doctor, regardless of whether it is heavy or not.

Possible pregnancy

If a few days after taking Postinor you start to have light bleeding that lasts for a day or two and then stops, take a pregnancy test. Perhaps it was implantation bleeding, which is often the very first sign of pregnancy. It begins six to twelve days after conception, and is sometimes mistaken for menstruation, although during normal periods the bleeding should not be spotting. Implantation bleeding, unlike menstrual bleeding, can be so weak that the patient can get by with simple daytime pads.

Fertilization of the egg occurs in the fallopian tube, through which the egg moves into the uterus after ovulation. The embryo, that is, the fertilized egg, enters the uterus only a few days after conception. Then it penetrates the wall of the uterus, and this can cause slight bleeding. During embryo implantation, a woman may also feel mild cramping in her lower abdomen. There are usually no other signs of pregnancy at this time.

If your pregnancy test is positive, make an appointment with your doctor immediately. Be sure to tell him that you took Postinor. There is little chance that this drug will cause any birth defects in the baby, so you will have a good chance of having a successful pregnancy.

In some cases, women develop an ectopic pregnancy after taking Postinor. It is unclear to what extent the use of this medication affects the likelihood of developing an ectopic pregnancy; be that as it may, any woman who decides to take Postinor should know its signs. An ectopic pregnancy may not cause any symptoms at first. A few weeks, and sometimes a couple of months after its onset, symptoms such as vaginal bleeding, nausea, vomiting, pain and/or severe cramps in the lower abdomen, pain on one side of the body, dizziness, and weakness may appear. If the fallopian tube ruptures, internal bleeding begins, which can lead to a sharp drop in blood pressure and fainting. If you suspect an ectopic pregnancy, you should seek medical help as soon as possible.

Any, even the most reliable and expensive contraceptive drug does not protect against unnecessary pregnancy 100%. And if there is a suspicion of its occurrence, Postinor will come to the rescue. The product is allowed to be used no more than once every 3 months. But even if used correctly, the reproductive system can work completely differently than before taking the pills. One of the signs of this is brown discharge that appears after postinor. Is this phenomenon common, or should a doctor be aware of it?

Emergency contraception is called such because it can work on any day. "Postinor" is a progesterone derivative - levonorgestrel. The substance is included in the drug in high concentration, therefore it stimulates one of the following possibilities:

inhibition of egg maturation;
thinning of the endometrium to minimize the possibility of implantation of a fertilized egg into it;
preventing sperm from entering the uterus.

All the properties of postinor ensure its ability to prevent an unwanted pregnancy from developing if its probability is high, but has not yet materialized. That is, it makes sense to use the product no later than 72 hours after sexual intercourse that is dangerous in this sense. It is equally effective at the stage before the ripening of the egg, on the day of its release and even after ovulation.

The use of the drug "Postinor" may be at least useless, and even threatening to health, if pregnancy has already taken place. Girls under 16 years of age should also not take pills without medical supervision.

The mechanism of action of Postinor on the woman’s body

Postinor is a synthetic progestin drug with a contraceptive effect. The effect is due to antiestrogenic and gestagenic properties. When taking the medicine in the first phase of the cycle, the active substance suppresses ovulation and prevents fertilization. There are also characteristic changes in the endometrium that do not allow the fertilized egg to attach to the uterine wall.

Postinor belongs to the so-called emergency contraception drugs. This means that it is used after sexual intercourse in the absence of contraception as such or if the contraceptive was ineffective. The need to take it may arise if the integrity of the condom is damaged.

The necessary contraceptive effect is due to the content of high doses of hormones. The main active ingredient in the drug is called levonorgestrel. Auxiliary components include:

potato and corn starch;
lactose monohydrate;
talc;
magnesium stearate;
colloidal silicon dioxide.

Each package contains 2 tablets of the drug.

Levonorgestrel causes certain changes in the functioning of the organs of the reproductive system:

inhibition of ovulation due to the lack of maturation of the egg and its descent into the fallopian tube;
reduction in the speed of sperm and their ability to fertilize when penetrating the genital tract;
stimulation of endometrial development and its subsequent rejection.

The contraceptive effect is due to the properties of the synthetic hormone included in the composition. A few days after taking the drug, bleeding is observed. Their average duration is up to 5 days.

Pregnancy is prevented in approximately 85% of cases. The effectiveness of contraception depends on the time interval between sexual intercourse and taking the pills:

95% – within the first day;
85% – during the second day;
58% – third day.

That is why you should take the pills as quickly as possible. The more time has passed since sexual intercourse, the lower the contraceptive effectiveness.

Indications and contraindications for use

The medicine is taken for the purpose of emergency contraception when contraception is unreliable or after unprotected sexual contact. Contraindications to taking pills include:

hypersensitivity reactions;
renal failure (severe);
pregnancy;
lactose intolerance;
glucose-galactose malabsorption.

How does Postinor affect menstruation?

The hormonal drug affects the reproductive system. In some cases, a cycle failure is possible, which manifests itself as a delay in menstruation.

How does Postinor work in the second phase of the cycle?

The contraceptive effect is accompanied by the occurrence of heavy bleeding, which occurs like menstruation. Bloody discharge is observed 7 days after taking the medicine.

The mechanism of action of Postinor depends on the phase during which the drug was taken. After taking the first tablet from the package, a significant amount of the hormone is released. In the second phase of the menstrual cycle, ovulation has already occurred. The effect of the drug has certain characteristics.

The second pill causes hormone levels to change again. After the end of the drug's effect, a sharp decrease in the concentration of hormones is observed. This causes excessive premature bleeding.

If you take Postinor during the second phase of the cycle, it acts as a drug that medically terminates pregnancy. The structure of the endometrium changes, and the fertilized egg cannot be implanted into the inner layer of the uterus. It is rejected into the lumen of the uterine cavity and exits with the next menstruation.

Can there be a delay in menstruation after Postinor?

Gynecologists emphasize that delayed periods after Postinor are common. The components of the contraceptive have a pronounced effect on the function of the organs of the reproductive system. That is why the drug can be used no more than 2 times a year, provided that the cycle is regular.

Why are there no periods after Postinor?

There are several reasons why your periods did not start after Postinor:

Increased blood clotting. The reason is typical for women with initially high blood clotting rates. In this case, both a delay and scanty periods are possible.
Incorrect use of contraception. A delay may occur if the timing of taking the pills is not met. The consumption of alcoholic beverages significantly reduces the contraceptive effect, which should also be taken into account.
Concurrent use of other medications. Some medications may reduce or increase the effectiveness of Postinor. The delay is caused by the use of Niverapine, Lansoprazole, barbiturates, Oxcarbazepine, and strong antibiotics.
Hormonal disbalance. Taking a drug containing an impressive dose of the hormone can cause failure even in gynecologically healthy women. A violation is considered harmless if the delay is no more than 7 days. In some cases, there is a premature onset of menstruation, which is also normal. Usually, early onset of menstruation is observed if Postinor is taken before menstruation. Using the medicine in the second phase of the cycle accelerates all processes occurring in the body.
Ignoring contraindications. The contraceptive cannot be used if you have liver or gallbladder diseases. Tablets are not recommended if you have a history of hepatitis. Taking medication may also cause deterioration in health.
Use by teenage girls. In adolescence, insufficient development of menstrual function is noted. The use of a hormonal drug often causes absence of menstruation and worsening of the condition.
Pregnancy. Contraceptive effectiveness does not reach 100% even with full compliance with all recommendations. If your period does not come within a month after Postinor, you need to rule out pregnancy.
Adverse reactions. A high dose of hormones causes headaches, drowsiness and skin rashes. Reactions from the digestive system, such as diarrhea, are sometimes observed. The occurrence of side effects may reduce the absorption of the active component and reduce contraceptive effectiveness.

What could be the consequences after taking Postinor?

Taking this medicine will affect the body, but if you follow the instructions for use and take it once per cycle, the consequences may be cycle disorders, which gradually normalize. Allergic reactions and unpleasant symptoms, such as nausea and dizziness, are also possible, which will also go away on their own. In such cases, no treatment is required. But if you violate the instructions and take the drug more than once a cycle, you risk your health. Repeated use will lead to severe hormonal imbalance, this effect will not necessarily occur for everyone, it all depends on the individuality of the body, but you should not take risks. The absence of a normal cycle, its constant changes and disturbances can lead to infertility.

Postinor affects blood clotting if used incorrectly and if recommended doses are exceeded. It can cause blood clots. This will be especially noticeable by women suffering from problems with blood clotting. The danger of blood clots is their ability to break off and block a vessel, preventing blood from moving. If this happens in the head or heart, a stroke occurs. Therefore, be sure to follow the dosage of the drug. An overdose will affect the functions of the liver; in case of liver diseases, the effect is even greater and worse on human health. If you have severe pain, heavy periods, or feel unwell, consult a specialist. During pregnancy, taking the drug can negatively affect the fetus; make sure you are not pregnant before taking it.

Based on the above, postinor is used in cases of emergency contraception, but this should be done in accordance with its instructions, in no case violating the dose and only in the next 72 hours after sexual intercourse without means of protection. Before use, you should make sure that there are no contraindications for use, ideally consult your doctor. And also remember about combinations with other medications. Do not use the drug twice in one month; it is better to use means of protection against unwanted pregnancy. Take time and visit a specialist with this question, because it is much better to prevent fertilization than to suffer later in finding solutions if you do not want children. Take care of your body, treat it with care, it is easier to prevent the risk of diseases than to treat them later.

How do your periods go after Postinor?

If you follow the instructions for the drug, menstruation delays and hormonal disruptions occur infrequently.

The onset of critical days depends on the phase during which the drug was taken. Your period may come a few days earlier or later than expected. As a rule, the early appearance of menstruation is associated with taking a contraceptive in the second phase.

After using Postinor, minor delays are sometimes observed. There is no need to worry if your period is no more than a week late.

How long does your period last after Postinor?

Usually, the use of emergency contraception does not affect the duration of menstruation. In some cases, the duration of menstruation changes both towards a reduction and an increase in the number of critical days.

A visit to the doctor will not be superfluous if there is scanty discharge accompanied by pain. These symptoms may indicate an ectopic pregnancy.

Scanty periods after Postinor

Slight brown discharge is characteristic of menstruation after taking Postinor. Levonorgestrel thickens the blood. It folds a little earlier and leaves the vessels of the uterine cavity more slowly. Pathology can be suspected if scanty brown periods are observed in subsequent cycles.

After Postinor, heavy periods

With heavy discharge, the accompanying symptoms are significant. Sometimes Postinor causes heavy periods. You should consult a doctor if your health suddenly deteriorates. If the pad needs to be changed every 3 hours, professional help is required to stop the bleeding.

After Postinor, periods do not end

The duration of menstruation depends on the individual characteristics of the female body. A hormonal drug can help increase the duration of critical days. Normally, the duration of menstruation should not exceed 8 days. Longer discharge is considered a side effect after taking the medication and requires consultation with a gynecologist.

My period came earlier after Postinor

Menstruation may come earlier after using a contraceptive. Some women emphasize that after Postinor, menstruation began within a week. Considering the composition of the drug and the nature of its effect on the body, this phenomenon is considered normal.

Delayed menstruation after Postinor due to simultaneous use with a hormonal contraceptive

A number of medications that are taken simultaneously with Postinor or taken regularly can completely neutralize its effect. If a woman takes medications for stomach ulcers (Lanosoprazole) or for HIV infection (Niverapin), then there is a high probability that a delay will occur while taking them. A negative effect can be produced by the simultaneous use of drugs containing St. John's wort, medications for epilepsy (Oxcarbazepine) and tuberculosis, as well as strong antibacterial drugs.

Delayed menstruation due to improper use of Postinor

In some cases, the effectiveness of Postinor is greatly reduced due to the fact that a woman drinks alcohol. If a woman takes Postinor, doctors recommend stopping drinking alcohol altogether, because... Alcohol can greatly affect the effectiveness of using such a drug.

Is it possible to induce menstruation with Postinor?

If there is a long delay, there is a need to take medications that help induce menstruation. For example, cycles lasting several months are observed against the background of PCOS.

Often the solution to the problem is to take hormonal drugs, which is considered a serious intervention in the female body. Normalization of the cycle should occur under the supervision of a gynecologist.

Some women use Postinor to induce menstruation ahead of schedule. This is strictly prohibited if pregnancy is suspected, the presence of an IUD, endocrine pathologies, or hormone therapy.

Instructions for use of Postinor for delayed menstruation

You can use the medicine on any day of the cycle. If your periods are irregular, pregnancy should first be ruled out.

Each package contains 2 tablets of the drug. The second tablet should be taken 12-16 hours after the first.

Pregnancy after using Postinor

When, during a delay in menstruation after Postinor, the test is positive, to make sure that pregnancy has occurred, be sure to do an ultrasound examination and test blood from a vein to determine hCG.

Once the result is confirmed, there is absolutely no need to fear for the health of the unborn baby due to the use of Postinor. This contraceptive is absolutely harmless and does not have negative consequences on the development of the embryo.

Such a pregnancy requires more careful monitoring in order to protect the expectant mother and her baby if any signs of abnormalities appear.

Modern medicine can have a huge impact on the normal development of the fetus and the condition of the pregnant woman herself. There is no need to panic, because everything is under control. If the birth of a new life was not prevented by contraceptive pills, we can conclude that the born child will grow up strong and healthy.

How to restore a cycle after Postinor

After using Postinor, the cycle often goes wrong. There may be delays, scanty or heavy menstrual flow.

The speed of cycle recovery is influenced by the following factors:

health status;
frequency of Postinor administration;
age;
compliance with the work and rest regime;
balanced diet.

Hormonal imbalance is usually observed with frequent use of pills, as well as in patients over 40 years of age.

Treatment is not carried out if there is a slight delay. After several cycles, the body copes with the consequences of hormonal emergency contraception on its own. Drug treatment is required if menstruation is absent for a long time after taking Postinor. Therapy is needed for cycle instability that persists for 6 months or more.

Hormonal imbalance and delayed menstruation after taking Postinor

As a result of the presence of an atypical amount of levonorgestrel in the blood, problems are observed in the functioning of the female reproductive system, even if there are no gynecological diseases. In this case, a delay of up to seven days is considered normal. Another extreme that occurs while taking the drug is the premature onset of menstruation. There is nothing wrong with this, as it fits into the norm. The medicine contains a hormone that controls the second phase of the female cycle. In other words, levonorgestrel is able to speed up all its processes, which brings the day of the onset of menstruation closer. This reaction increases if the drug is taken in the luteal phase, when the natural amount of gestagens is very high.

The presence of severe hormonal imbalance can be observed under different circumstances, but there is a high probability that this will occur in women with hormonal problems or while taking Postinor. If such phenomena occur after taking the drug, you should definitely see a doctor.

Possible side effects

The impact of emergency contraception has a negative impact not only on the functioning of the reproductive system. Sometimes after Postinor there are no periods with a negative test. Systemic side effects include:

rash, swelling, itching and other allergic manifestations;
vomiting, diarrhea, nausea;
headache or dizziness;
fatigue.

Reactions related to dysfunction of the reproductive system are very often observed. The patient may experience pain in the lower abdomen, bleeding, swelling in the mammary glands and delayed menstruation.

Reviews of Postinor for delayed menstruation

In numerous reviews about Postinor, women are interested in when their periods should begin. As a rule, the time of onset of menstruation varies from person to person.

The drug Postinor is a well-known means of emergency contraception. Despite the fact that the consequences of taking it can be very negative, it does not lose its popularity.

Very often, women have hormonal imbalances after taking Postinor, and menstruation may come completely at the wrong time. In order to figure out when to expect the next menstruation and what to do in case of a malfunction, it is worth reading useful information.

Should there be bleeding after postinor?

Bleeding from the postinor should begin on day 6-7. This is a normal phenomenon that is associated with the effect of a large dose of levonorgestrel on the body. The onset of bleeding indicates that the contraceptive drug has worked.

The mechanism of action of postinor is based on blocking the release of a mature egg from the ovary.

Lack of ovulation leads to the impossibility of conception. In cases where unprotected sexual intercourse occurred after ovulation, postinor affects the uterine mucosa, preventing the fertilized egg from being implanted.

It must be remembered that postinor exhibits its effect only when it is necessary to prevent pregnancy. If it has already occurred, then the large dose of the hormone contained in the postinor will not work.

The rules for taking the drug are simple. The first tablet should be taken as quickly as possible after sexual intercourse, which ended with ejaculation into the vagina. The next one is between 12 and 16 hours after taking the first dose. In cases where a woman does not have time to take the second dose of the medicine within the specified time, the effectiveness of the drug is reduced.

There are a number of contraindications for taking postinor:

allergic reaction to the components contained in the drug;
serious disturbances in the functioning of the liver and gallbladder;
pregnancy;
the presence of blood clots in arteries and veins;
bleeding from the genitals, the cause of which is not clear.

Girls under 16 years of age need to consult a gynecologist before taking Postinor. It is extremely rare that after consultation with a specialist, postinor is allowed to be taken by women who are breastfeeding their children. In such cases, they should take two tablets at once and skip the next feeding.

After taking Postinor, there is a possibility of some side effects. Most often among them there are rather weak bloody or brown vaginal discharge. The following phenomena are observed less frequently:

nausea, vomiting, diarrhea;
soreness in the area of the mammary glands, their swelling;
headache, fatigue.

Such conditions do not require contacting a specialist. But if a woman has difficulty breathing, she notices a rash on her body, which is accompanied by severe itching, as well as swelling of her face, this may indicate an allergic reaction to the drug. You need to see a doctor. It is worth doing the same if the vomiting does not stop, there are signs of severe bleeding and abdominal pain.

Taking the drug and bleeding

The drug Postinor provokes bleeding quite often. Sometimes bloody discharge appears soon after a woman takes the pill. It happens that this happens a few days after taking the second dose of the drug.

Most often, bleeding is associated with improper use of the drug or violation of the specified dosage. Having taken more than two tablets or not being able to wait between the first and second doses, a woman may notice that she is bleeding. In this case, uterine bleeding is quite profuse. It can last longer than expected (up to 5-7 days), often stretching to a month.

Bleeding is associated with hormonal imbalance. A large dose of levonorgestrel causes the lining of the uterus to thicken, which leads to so much bleeding.

Heavy bleeding after taking the drug not only creates inconvenience for a woman when she constantly needs to change pads. It may not have the best effect on her general condition. Manifestations such as weakness, dizziness, pale skin, rapid heartbeat, and even more so loss of consciousness should be a reason to immediately consult a doctor.

How to stop bleeding

In each case, the doctor individually determines the method to stop the bleeding associated with taking postinor. Hemostatic drugs are often used: Dicynon, Vikasol. If there is a large volume of blood loss, transfusions of blood substitutes and sometimes blood or its components are prescribed: red blood cells, plasma.

If medical methods fail to stop the bleeding, doctors have to use surgical techniques.

The principle of action of the drug

Before answering the question of when your period will come after Postinor, it is worth understanding why this medication gives the desired effect.

https://youtu.be/1BaPjWViPsw

The drug has the following features:

It contains levonorgestrel, which is a synthetic progesterone. This powerful hormone is also found in smaller quantities in other contraceptives. The amount of levonorgestrel in one Postinor tablet is the same as in 20 tablets of oral contraceptives.
The medication begins its work within 24 hours after complete dissolution in the intestines occurs.
After taking it, a woman may experience bleeding similar to normal menstruation. Most often this happens within three days. This effect is caused by the powerful contraceptive effect of the drug.
If the drug was taken before ovulation, the maturation of the egg is blocked.
If sexual intercourse occurs after ovulation, Postinor causes an abortive effect. The structure of the endometrium changes and the egg is rejected.
The second tablet of the medication gives the female body a huge amount of gestagen. When the drug loses its effect (after 2-5 days), the hormone content decreases sharply. As a result of such a shake, premature hemorrhage occurs.
Such discharge is not normal menstruation after taking Postinor. The period when menstruation should begin depends on the woman’s individual cycle. Critical days may come with slight deviations.

Delay after Postinor with a negative test

When there is a delay after Postinor, and the test is negative, but you have doubts about its truthful answer, you need to visit a doctor to rule out an ectopic pregnancy. Since this pathology is a very common occurrence when taking contraceptives, extra insurance will not hurt.

There is a delay after Postinor, and the test is negative can be due to an ectopic pregnancy; to exclude it, it is necessary to take a blood test for hCG

If after Postinor the delay is already a month

If pregnancy is excluded, the delay after taking Postinor is explained by:

The mini-abortive effect of levonorgestrel, changing hormonal levels in such a way that the normal functioning of the uterus, ovaries, fallopian tubes is disrupted, interfering with the timely onset of monthly bleeding, postponing their onset indefinitely, therefore, after Postinor, a delay of a month is not such a rare occurrence;
The presence of endocrine diseases;
Various gynecological inflammatory processes, such as colpitis, vaginitis, adnexitis, endometritis, etc.;
Some pathologies of the urinary system, in which there may also be a delay after taking Postinor.

It happens that after Postinor there is a delay of a month and if pregnancy is excluded, this means that the functioning of the uterus and ovaries is impaired. This can ultimately lead to gynecological diseases.

How many days is the delay after Postinor?

No specialist can say for sure how many days the delay after Postinor will be when these diseases are detected. It all depends on their course and the severity of symptoms. In any case, if menstruation does not come within 14 days, you must contact the antenatal clinic in order to find out in time the cause of the rhythm failure and begin to correct it.

It is difficult to say how many days there is a delay after Postinor in the presence of gynecological diseases, but if menstruation does not appear within two weeks, you need to contact a gynecologist

Impact on the female body

The medication has its side effects.

most common symptoms that occur are:

Stomach ache.
Nausea and vomiting.
Dizziness.
Allergy.
Hormonal imbalance.
Irregular menstruation.

All these phenomena are provided for in the standard instructions for the drug.

However, there may be other side effects that should never be ignored.

For example, severe prolonged bleeding. If the discharge does not stop for a long time , you should seek medical help as soon as possible.

Contraindications for use

There are restrictions under which this drug cannot be used.

These factors include:

Lactation period.
Pathologies of the bile ducts, kidneys, liver.
Thrombosis.

Age less than 16 years.
Intolerance to individual components.

It should be remembered that this drug is an emergency remedy.

Its use is possible as a last resort and very rarely (in no case more than once a month).

Normalization of the menstrual cycle

Taking the drug can lead to two conditions: a delay in menstruation or bleeding. In some cases, these phenomena may be a cause for concern, but most often such symptoms are a completely normal reaction of the body to Postinor.

If the medication succeeds in blocking ovulation, menstruation may begin a week after taking the drug.

This happens if the substance has taken effect and no problems with hormonal levels are observed.

There are cases when menstruation lasts more than 10 days .

It may appear as a scanty brown discharge.

This is a deviation from the norm and a reason to seek medical help.

In general, the time when menstruation should begin after taking Postinor is a very individual factor.

Sometimes there may be a delay in critical days. An artificial hormone can shift the cycle by 7 days.

If, after a week, “these” days have not arrived, the question of when menstruation begins after taking Postinor should be asked to a gynecologist.

In addition, you can go to the pharmacy or send someone close to you for a pregnancy test.

It should be remembered that the test does not always give the correct result.

If there is a hormonal imbalance in the body, it would be best to do a blood test for hCG .

It gives fast reliable answer and is 100% reliable.

It happens that after taking the medication, additional treatment may be required to normalize hormonal levels. Before using the drug, you should consider all the pros and cons and make the most informed decision.

Last update: 02/10/2019

It happens that unplanned events occur in a woman’s personal life that require urgently taking emergency contraceptive measures: a sudden impulse of passion or, God forbid, rape. Then Postinor comes to the rescue - a drug that eliminates unwanted pregnancy due to the content of the hormone levonorgestrel. Taking the pill in a timely manner after unprotected intercourse in 95% of cases prevents fertilization of the egg. However, the price of such convenience is hormonal disorders in the body that affect the menstrual cycle: menstruation after Postinor changes the date of arrival, the nature and amount of discharge.

How the drug works

Emergency contraception triggers the mechanism of action in several stages, it all depends on the time of taking the pill:

At the earliest stage, Postinor delays the ovulation process. In this way, the egg is not fertilized and there is no conception;
At the second stage, the activity of the penetrating sperm is affected, they become lethargic and inactive;
The last stage assumes that the pill was taken 2-3 days after unprotected sexual intercourse. In this case, the ovulatory process has already started, the drug directs its action to the functional layer of the endometrium. It modifies its structure, thereby reducing the chance of successful implantation of the fertilized egg to a minimum. In fact, this stage is considered an abortion.

Action of Postinor

To figure out when to expect your period after taking Postinor, you should understand the principle of action of the drug. The contraceptive effect is achieved by increasing the concentration level of levonorgestrel, which causes the following reactions of the reproductive system:

delayed ovulation - the hormone inhibits the maturation of the egg and its release from the ovary;
sperm that enter the female reproductive system lose activity and ability to fertilize;
provoked by a hormonal surge, the endometrium begins to be rejected.

Postinor as emergency contraception

Emergency contraception has its effect in several stages:

The first is delayed ovulation. As a result of the first stage, the egg does not move from the ovary. Thus, an egg that cannot enter the fallopian tube is not prepared for fertilization;
The second stage - the main active ingredient affects not only the ovulation of the egg, but also the speed and functionality of sperm;
The third stage is a direct effect on the endometrial layer of the uterus. After using the drug "Postinor", the normal structure of the uterus, its functional features and the internal active layer change. Thus, the ability of the uterus to shed the inner layer of the uterus changes, this is the reason why there is no menstrual flow. In this case, the test for determining human chorionic gonadotropin will be negative.

When to expect your period

In women who do not have serious health problems, cycle disruption after Postinor is usually insignificant; the date of menstruation will largely depend on the phase in which the pill was taken. Your period may begin within a week after taking it, or it may not come even after a month in case of severe hormonal imbalance.

Considering that Postinor delays ovulation, a slight delay is natural, but no doctor will say how many days it will be. The absence of menstruation for more than 5 days from the expected start date should be considered a cause for concern. To exclude negative consequences, you need to take a home pregnancy test and go to an antenatal clinic. When an “interesting situation” is established, you should under no circumstances take the contraceptive again.

Sometimes women claim that taking the drug caused their periods ahead of schedule. Such a statement contradicts the principle of action of the active substance; spotting is explained by the release of the endometrium or the opening of bleeding (if there is a lot of blood). In the latter case, you should immediately seek help from a hospital; it is almost impossible to stop the bleeding on your own.

Reasons for rejection

If your period is delayed by 5 days, it is better to take a pregnancy test. Often the reason lies precisely in pregnancy.

If a girl takes Postinor tablets 3 days after intercourse, it is quite possible that pregnancy has occurred. After all, the instructions clearly indicate: take the medicine within 72 hours.

But there may be other sources:

A delay in menstruation may be due to a hormonal imbalance in the body;
Diseases caused by an infectious nature;
A delay may occur due to an allergic reaction to the composition of the drug.

In addition, it is possible that contraindications to taking Postinor were not taken into account, which caused disruptions in the cycle:

The girl's age is up to 16 years. Young ladies should be doubly careful - the consequences can be fatal, including infertility;
Unstable menstrual cycle of a woman in general;
If there are diseases of the liver, kidneys, gall bladder, chronic diseases of the genitourinary system.

Important: before taking the drug Postir, carefully read the instructions and contraindications!

Frequent use of the drug may cause undesirable consequences:

Ectopic pregnancy;
Heavy periods caused by a “horse” dose of gestagen, suppressing progesterone and pituitary hormones. Under its influence, the uterus rejects everything that has accumulated, and this increases blood loss. In this case, it is better to seek help from a doctor to avoid consequences, for example, iron deficiency anemia.
Severe and prolonged blood loss. Most often, they occur in women with unstable hormonal levels. Therefore, if you change hygiene products more often than every 3 hours, you should consult a gynecologist.
Severe pain in the lower abdomen should also be a reason to consult a specialist.

Reasons for delay

A delay in menstruation after Postinor is observed in the vast majority of cases. Levonorgestrel has a strong, sometimes unpredictable effect on the female body. There are several reasons for the fact that periodic bleeding does not come on time when it should, being significantly delayed:

Violation of the terms of taking the drug prescribed in the annotation. Pregnancy could occur;
Increased blood clotting rate. Menstruation does not begin because the vessels do not release blood;
Drinking alcohol while using Postinor;
The parallel use of other medications can neutralize the contraceptive effect, which can lead to fertilization of the egg;
Hormonal imbalance, in this situation it’s normal for a week. A failure can cause menstruation ahead of schedule, there is nothing wrong with that;
Severe hormonal imbalances. Often observed with abuse of emergency contraception. It will take more than one month to restore the normal functioning of the reproductive system;
A delay in menstruation after taking Postinor occurs due to contraindications to it;
Gynecological diseases, endocrine abnormalities.

Even if all of the above reasons are excluded, and there is no period, you should not postpone a visit to the gynecologist: there is a possibility of an ectopic pregnancy, which is difficult to recognize on your own.

A separate issue is the use of Postinor by teenage girls. Often, young ladies do not care about protection in advance, and after unprotected sexual intercourse they use emergency measures, being confident in their safety. This behavior is wrong: the hormonal background, which has not yet reached balance, changes significantly. The first reaction of an immature organism is general malaise, and later pathologies of the menstrual cycle are observed.

Admission rules and recommendations

It makes sense to take the drug when there is reason to fear an unwanted pregnancy, that is, after unprotected sexual intercourse. In order for the pill to be taken to give the desired result, Postinor is taken in the following mode:

No later than 24 hours after full sex. Then the effect is detected in 95% of cases.
In a period of time from 24 to 48 hours, counting from “dangerous” sexual intercourse. Women who use the drug according to this regimen do not become pregnant in 85% of cases.
49 - 72 hours after coitus. Then the contraceptive effect is reduced to 58%.

To prevent unwanted pregnancy, you need 2 tablets of the product. They drink one at the already indicated time (the first option listed is preferable). 12 hours after it, the woman should take the second Postinor tablet.

If the timing of pregnancy protection with its help is missed, using the drug may be pointless.

Before using a contraceptive, you should carefully study the instructions for it, in particular, the section on contraindications and adverse reactions. Failure of menstruation after postinor, sometimes observed by girls who have used it, causing many fears and questions, can be provoked by both.

Features of menstruation

When menstruation begins after Postinor, its character and course can surprise and even frighten a woman. To avoid unnecessary stress, it is better to familiarize yourself with possible deviations in advance:

A large amount of levonorgestrel can cause periods that are brown in color and very scanty in volume. The situation is normal for the first cycle after taking the drug: the blood thickens, leaves the vessels more slowly, and its oxidation begins. If everything repeats through a cycle, you need to consult a doctor;
Significant increase in the duration of menstruation to 8-9 days. Hemostatic agents may be needed. The longer your period lasts, the greater the likelihood of developing pathology;
Change in volume up or down. Usually observed against the background of deterioration in health. You should not endure it to the limit; it is better to consult a specialist. The need to change the pad more often than every 3 hours indicates bleeding;

There are 3 reasons that can cause menstruation with similar deviations:

age up to 16 years;
previously observed hormonal changes;
the cycle was not stable initially.

It is best to discuss any questions that arise with your doctor.

What to do if there is a delay?

What to do if your period doesn’t come after Postinor? Doctors recommend immediately doing a rapid test or donating blood to determine the level of hCG. If the results are negative and pregnancy is not confirmed, it is important to undergo a gynecological examination as quickly as possible and figure out why there are no menstrual days. The most common causes of amenorrhea:

disruption of ovarian function, which will take about 3 months to recover;
disruptions in the hormone secretion system, which subsequently leads to anovulation and the inability to conceive naturally;
Frequent (several times a year) use of the drug, as a result of which ovarian dysfunction developed.

There are other factors that may influence the absence of menstruation. It is important to consult a specialist on this issue. General recommendations for women:

maintaining a healthy lifestyle;
balanced diet;
use of hemostatic drugs for bleeding;
taking vitamins.

Postinor is a means of emergency protection against conception. It can be used no more often than once every six months. The correct thing to do would be to completely abandon such a pharmacological product. A woman who has regular sexual intercourse should take care of long-term protection against pregnancy. For those who have not yet found a permanent partner, it is better to use barrier contraception.

In most cases, the correct use of the drug “Postinora” does not pose any danger or malfunctions. But even if the woman does not violate the instructions for the drug, anything is possible. Therefore, it is worth considering not only delays, but also other difficulties, as well as options for action if they arise:

After postinor, menstruation is brown and in smaller volume than usual. This is a common occurrence caused by the presence of levonorgestrel in the body. It thickens the blood, causing it to clot and leave the vessels of the uterine mucosa more slowly. The discharge becomes brown because this is what oxidized biological fluid should be. Questions may arise if this is observed in subsequent cycles. Then you need to go to the gynecologist to get examined.
Delay of menstruation by more than 7 days. When, after taking Postinor, menstruation begins during this period, it does not matter. They can go both on the first and on the seventh day. Both options are normal. But if you still don’t have your period, you should do a home pregnancy test. An hCG test done in a clinic will be even more informative, since a self-check tool can give false information about its absence. If Postinor does not have the expected effect, you will have to get rid of the pregnancy in another way or decide on preservation. But here a visit to a gynecologist is inevitable.
Prolonged discharge. How long menstruation lasts after postinor depends on the characteristics of a particular organism. Given the strong hormonal influence of the drug, they can be observed for up to 7 - 8 days. Anything longer is considered an unwanted side effect, although it is not uncommon. Long-lasting discharge can be dealt with with tincture of water pepper and nettle decoction. But it’s better to go to the doctor and take his recommendations on how to stop them.
Changes in the volume of menstruation. What kind of menstruation after postinor is also determined not only by the influence of the drug, but also by the individual characteristics of the reproductive system. The discharge may be more intense than usual, or, on the contrary, sparser, accompanied by unusual sensations. It is important that this does not cross the boundaries of the norm when health deteriorates sharply and unbearably. That's when you really need a doctor. If menstruation after postinor is heavy, the need for its help is also determined by the volume of discharge. Filling each pad in less than 3 hours will certainly require professional methods and means to stop the bleeding.
