Will a pregnancy test tell the truth if you take it during the day or evening?

How pregnancy tests work

Diagnosis of pregnancy using a test is based on the detection of a special hormone in female urine - human chorionic gonadotropin, the production of which actively begins on the 6th day after fertilization of the egg. When a biomaterial containing hCG comes into contact with the reagent, an indicator coloring reaction occurs, which with a high probability indicates the occurrence of conception.

The level of human chorionic gonadotropin begins to increase from 6-10 days after fertilization. Having reached its peak in the second trimester, its quantity begins to decline.

Dynamics of hCG growth

The reliability of the test and its ability to determine pregnancy at the earliest stages directly depends on the level of sensitivity, measured in milli International units per 1 milliliter - mIU/ml. In modern rapid tests, this indicator varies between 10-25 mIU/ml. The lower the specified parameter, the more sensitive the indicator reacts, therefore, it is possible to detect fertilization at the earliest stages (11-12 days from the moment of ovulation). Only a biochemical blood test can provide a more accurate diagnosis, since the concentration of hCG in it increases a little earlier.

The standard test sensitivity of 20-25 mIU/ml with the maximum degree of reliability detects an increased level of the hormone already on the 1-2 day of a delay in the menstrual cycle.

Confirmation methods

Determining pregnancy is not a simple process. There are three fundamentally different methods for confirming successful fertilization. These include:

• Determination of a pregnancy-specific hormone in a woman’s blood or urine.
• Visualization of the fertilized egg or embryo using ultrasound examination of the uterus.
• Confirmation of pregnancy during examination by a gynecologist.

What method should an expectant mother use to get a quick and accurate result?

As a rule, women do not rush to see a gynecologist for many reasons. Instead of visiting a antenatal clinic, expectant mothers think about an ultrasound or hormone determination. What to give preference to?

Ultrasound could be considered an ideal method for confirming pregnancy if it were reliable in the early stages, from the first day of the delay. But this study becomes informative no earlier than the fifth week of gestation, and often later.

A hormonal test can quickly and accurately confirm the success of conception.

Pregnancy hormone

Human chorionic gonadotropin is one of the pregnancy hormones. It begins to be produced almost a week after fertilization and is soon detected by laboratory test systems.

The first way to determine human chorionic gonadotropin in a woman’s body is by biochemical analysis.

To perform it, you need to donate blood from a vein on an empty stomach. The appearance of the hormone in a significant concentration indicates that conception was successful. This analysis can be carried out even before your period is missed. Human chorionic gonadotropin is usually determined only in commercial laboratories and this study is not cheap.

Is there an alternative to hormonal blood testing that works from the first day of the delay?

Alternative test

Probably every woman knows that pregnancy is easily confirmed by a regular pharmacy test. But not everyone understands the principle of operation of this alternative method.

A pharmacy test is also a determination of human chorionic gonadotropin.

But unlike laboratory analysis, in this situation urine is examined. This is how the hormone is eliminated from the body. Its concentration in urine will always be less than in the blood. This is especially true for the early stages – the first weeks of gestation. When the laboratory blood test is already positive, the pharmacy test will most likely still show one line. However, it has undeniable advantages.

Advantages

What are the advantages of a pharmacy test if it is inferior to a blood test in terms of information content? Although you need to use this method a little later, it is more convenient to do so for the following reasons:

• The pharmacy test is available during the day and evening.
• Its cost is significantly lower than a blood test.
• The result can be found out in 3-5 minutes, and it is clear - in the form of stripes, not numbers.

But in order for the pharmacy test to be as informative as possible, you should use it correctly.

Reasons for the unreliability of determining the presence of pregnancy

Despite the high degree of reliability of modern express studies, when determining the presence of pregnancy, false positive or false negative results can often occur. In each individual case, the reasons for the error may be different.

In rare cases, test readings may be incorrect

To reduce the likelihood of errors during diagnosis, it is recommended to repeat the test after 2-4 days.

Reasons for a false positive test result:

• some diseases and disorders in the functioning of internal organs and the endocrine system, in particular ovarian dysfunction;
• taking hCG-based medications 2 weeks before the study;
• an attempt to diagnose pregnancy less than 2 months after childbirth, miscarriage or abortion;
• expiration of the test’s shelf life or non-compliance with storage conditions (violation of the seal of the packaging);
• the presence in the body of tumor formations that produce the hormone human chorionic gonadotropin;
• omission of more than 10 minutes after the start of the diagnosis (for certain types of tests).

Factors influencing the detection of a false negative result:

• an attempt at early diagnosis carried out before the recommended period indicated on the package;
• disruption of the endocrine system;
• reduced hormone levels associated with the individual characteristics of a woman’s body;
• violations of the diagnostic procedure;
• expiration date;
• failure to comply with storage conditions or failure to seal the packaging;
• taking certain types of medications the day before the test.

Two reasons to know

Women want to know about their pregnancy, either if they are not yet ready for such changes, or, on the contrary, they are looking forward to them.

If you dream of pregnancy, it is important to monitor your health and nutrition before it occurs. Refrain from alcohol and smoking, normalize your weight. If you have a sedentary job, you should walk more. You can find more detailed recommendations on what to do while waiting for conception in the Memo for Expectant Mothers on our website.

It is also important to provide the body with certain substances even before pregnancy. For example:

• Vitamin B9 (folic acid) is needed in the first 3 weeks after conception, when a woman is just beginning to suspect that she is pregnant. Folic acid is responsible for the normal formation of the neural tube and circulatory system.
• Iodine is part of hormones that regulate the formation, development and growth of the fetus. Lack of iodine can cause serious disorders, including deafness, cretinism, and developmental delays in a child.
• Omega-3 affects the formation of the brain, the development of nervous tissue, and visual organs. With a lack of omega-3, children are more prone to allergies and hyperactivity.

To prevent problems associated with a lack of components important during pregnancy, it is recommended to take vitamin and mineral complexes even before pregnancy. In particular, Pregnoton Mama contains iodine, folic acid, liposomal iron (which is absorbed better than traditional forms of iron), omega-3 and other substances necessary for expectant mothers.

If the test does not show the desired result for a long time, pay attention to the drug Pregnoton, which is designed to increase the likelihood of conception. It contains vitamins, minerals, vitex extract and the amino acid L-arginine - together these components improve female fertility.

THIS IS NOT AN ADVERTISING. THE MATERIAL WAS PREPARED WITH THE PARTICIPATION OF EXPERTS.

Preparing for the test

All existing types of express tests are based on the principle of detecting the hCG hormone in biomaterial (urine).

Popular types of tests

In order to eliminate possible inaccuracies in determining pregnancy, it is advisable to follow several recommendations:

• use only tests of the appropriate expiration date, packaged in airtight packaging;
• the package must be opened immediately before the test;
• rapid tests are for one-time use only. If for some reason the indicator gave incorrect readings the first time, there is no point in trying to diagnose it again;
• The highest concentration of the hCG hormone accumulates in the body during the night, so according to the instructions, it is better to take a pregnancy test in the morning;
• It is advisable to wash yourself before urinating;
• collection of biomaterial is carried out in clean containers;
• following the instructions, lower the indicator into the liquid only to the specified level;
• it is necessary to strictly adhere to the diagnostic time;
• compare the diagnostic results with the accompanying instructions for the pregnancy test.

If there is a long delay in the menstrual cycle in conditions where the pregnancy test shows a negative result, a blood test will help to identify the presence of the hCG hormone in the body.

How to properly conduct a rapid examination

The reliability of the results will also be influenced by external factors. To find out for sure whether it’s time to prepare to become a mother, you need to take the following steps:

1. Inspect the packaging for damage.
2. Check the expiration date of the product.
3. Prepare a clean container and create conditions as close to sterile as possible.
4. It is better to use morning urine, but if you have not had your period for a long time, then any time of day will do.
5. Wash and dry your hands before starting the test.
6. Take out the test strip and lower it to the indicated level.
7. Place it on a dry towel or napkin.
8. The result can be seen in one to three minutes.

Types of pregnancy tests

Regardless of the level of sensitivity, pregnancy tests also differ in design and method of use:

• strip strips - narrow paper strips impregnated with a reagent containing antibodies to the hormone, are considered the most popular and affordable type of test, which, despite its low cost, is characterized by high diagnostic reliability.
• flatbed - are a modified format of strip strips, enclosed in a plastic block with two windows.
• inkjet - similar to a mini-case, at one end of which there is an indicator that does not require collecting urine in a container, but conducts diagnostics upon contact with biomaterial during urination. The indication is displayed in a separate window.

Jet pregnancy test

• electronic-digital - highly sensitive miniature devices with a simple system for collecting biomaterial, in which the result is displayed on a mini-liquid crystal screen. Certain types of devices are compatible with a PC and allow you to determine the approximate gestational age with a high degree of probability. They are considered one of the most expensive.

Early pregnancy symptoms

In the early stages, to confirm the onset of conception, a girl should pay attention to such manifestations as a constant desire to lie down, the appearance of chronic fatigue, and frequent mood swings. Fertilization is often accompanied by increased vaginal discharge. They may be profusely mucous in nature. It often happens that a woman observes minor spotting. This symptom indicates the attachment of the fertilized egg to the wall of the uterus (implantation). In addition, the manifestations are of the following nature:

• The appearance of a pulling sensation in the lower abdomen.
• Increased breast sensitivity.
• Change in taste.
• Increased sense of smell.
• General fatigue, drowsiness.
• Increased tearfulness and irritability.
• Nausea and dizziness, which occur mainly in the morning.
• Increase in body temperature to 37-37.2°C.

Another common sign of fertilization is a disorder of the digestive system. This happens against the background of hormonal changes, as a result of which the walls of the stomach and intestines lose their tone and peristalsis worsens.

Strip strips

Since these express tests do not include a special container for collecting biomaterial, it must be prepared in advance. You need to collect a little urine in a clean, dry container and lower a paper strip into it for a few minutes to the mark indicated on its base. You can judge the presence or absence of pregnancy no later than 10 minutes. A positive result is marked as 2 parallel lines, a negative result as one.

Strip pregnancy test

What is hCG?

HCG (HCG) is a hormone that is normally produced by the human body only after pregnancy. It begins to be produced from the moment of implantation of the fertilized egg. As the embryo develops, the level of HCG gradually increases and reaches its maximum levels by the end of the first trimester - at the 11th obstetric week. Then it slowly decreases.

Determining pregnancy using soda

All modern pregnancy tests used by women at home, as well as traditional methods, are designed to determine the concentration of hCG.

Inkjet view

Due to the absence of the need to collect liquid in a separate container, inkjet pregnancy indicators are considered one of the simplest and most convenient to use. To carry out the procedure, simply place it under a stream of urine for 5 seconds. Diagnostics can also be carried out in the standard way by placing the tip in a container with biomaterial. The result will be displayed within 10 minutes (the time depends on the overall hormone level) in the form of one or two stripes. High sensitivity allows you to determine the presence of conception at the earliest stages.

Signs and signs by which conception can be determined

From generation to generation, women pass on signs by which one can almost unmistakably suspect an imminent addition to the family. Moreover, this can be done even before the start of the expected menstruation without pharmacy tests. Let's look at the most common and reliable signs:

• Changing a woman's taste preferences. For no apparent reason, a girl may suddenly be drawn to salty, sour, spicy or, conversely, sweet. This is explained by an increase in hormone levels in the body and changes in water-salt balance.
• Increased sense of smell. Some smells that the girl previously tolerated quite well may now seem disgusting to her. The sense of smell can be irritated by detergents, perfumes, certain foods, and more.
• Nausea and vomiting often occur in the morning. This condition is called toxicosis.
• The soreness of the mammary glands increases. In addition, the breasts increase in size, and the nipples darken and become rougher.
• Pigmentation may appear from the navel line to the pubis. At first, the strip has a barely noticeable outline, later it becomes more pronounced and disappears only after childbirth.
• Instability of the emotional background appears. A woman can cry over trifles, worry about little things, and feel unprotected.

At later stages, a sign such as frequent urination appears. Many girls mistakenly believe that they have cystitis. In addition, sexual desire may increase or, conversely, decrease. It is worth noting that one of the main signs that allows you to accurately determine whether pregnancy has occurred is morning sickness.

Diagnosis of abnormalities using a rapid test

A simple pregnancy test system can detect not only the fact of fertilization, but also various problems and pathologies.

An increase in hCG levels can occur not only during conception, but also in non-pregnant women, as well as in men. Such a deviation may indicate a number of serious diseases. Among them:

• tumor formations in the testicles in men;
• pathologies associated with tumor formation in the gastrointestinal tract;
• malignant and benign tumors in the respiratory and genitourinary systems;
• molar pregnancy or hydatidiform mole;
• malignant trophoblastic tumor.

Increased hCG levels are also possible in men

Tests in which the second stripe is clearly paler than the first also deserve special attention. This indicator may indicate a reduced level of the hormone human chorionic gonadotropin. This condition is possible in the early stages of conception or in cases of frozen pregnancy.

If you have any doubts about your health, it is better to immediately consult a specialist.

The most reliable methods

You can check whether a girl is pregnant or not even before her period begins using simple but effective methods. In this case, you will have to use soda or iodine. In addition, a mercury thermometer can be used. A girl can easily use this diagnostic method herself at home. So, let's look at each type of diagnosis in more detail.

Basal temperature measurement

By measuring body temperature in the rectum itself, it is possible to suspect the onset of conception. To do this, you should count a few days from the date of menstruation and start measuring your temperature. During ovulation, basal temperature usually rises to 37-37.2 °C. Before the onset of menstruation, it decreases. If this decrease does not occur and the thermometer remains elevated, there is reason to believe that conception has occurred.

You might be interested in: What are good pregnancy tests?

It is best to carry out the measurement procedure in the morning immediately after sleep, without getting out of bed. It is recommended to do this at the same time, for example, at eight o'clock. The time for measuring temperature in the rectum is 5-7 minutes.

Women planning a pregnancy are advised to constantly measure their basal temperature and keep a special diary. This will help determine what changes occur in the body throughout the cycle.

Soda

You can determine whether conception has occurred at home using regular baking soda. It has been scientifically proven that when pregnancy occurs, the acid-base balance of urine begins to change. To conduct the study, it is recommended to collect the morning urine sample in a sterile container. The vessel can be boiled first. Add a teaspoon of soda to the urine and observe the reaction. If the soda remains at the bottom and no reaction is observed, then there will be a replenishment. If hissing and bubbles appear in the urine, it can be assumed that there is no pregnancy.

We must not forget that changes in the acid-base balance can be observed not only during pregnancy. A decrease in Ph may indicate acute infectious diseases in the kidney area or other pathologies.

How to recognize pregnancy without a test using iodine

There are two simple methods that allow you to quickly confirm or deny conception at home. You can make them yourself. They both involve the use of urine and iodine. To carry out such a diagnosis, you will need morning urine. The check is carried out like this:

• Soak a small clean piece of paper in urine and drop a drop of iodine on it. If the leaf turns bluish or purple, the woman may be pregnant. With a brown color, there is no conception.
• The second method involves using urine in a container. In this case, you need to very carefully drop a drop of iodine into it and monitor the reaction. If the drop sinks and then surfaces a little, there is reason to believe that the woman will soon become a mother.

Both methods are based on changing the acid-base balance of urine, hCG and the hormonal levels of the body.

Due to the fact that these indicators may change under the influence of other provoking factors, for example, under the influence of various diseases, these methods cannot be considered 100% reliable.

At what stage does the test show pregnancy after conception?

As you know, a woman can become pregnant within about a week of the entire menstrual cycle (of course, this is not an axiom) - 3-4 days before ovulation and 3-4 after it.

Over the next ten days, that same “pregnancy hormone” begins to rise.

Another ten years after intercourse you can go to the pharmacy.

For the result to be correct, it is better to carry out the analysis after a couple of days of delay.

Things are more complicated with an irregular cycle - determining exactly whether ovulation occurred is problematic.

This means that there is no point in purchasing a test before the expected delay.

In this case, you need to wait for the approximate onset of menstruation and, if the result is negative, conduct rapid testing.

Most instructions say in black and white that the test shows the exact result after the first day of delay.

Of course, there are situations when there is not enough patience to sit and wait, replenishment was not planned, and ladies run to the pharmacy the day after intercourse, which is completely pointless.

There are many tests for home use

Even if you go to the clinic for a routine urine test to check the level of the same hormone, it will take a week for it to rise and another day to wait for a response from the laboratory.

Tip: pay attention to the brightness of the stripes. With a small excess of hormone concentration, the second stripe may be pale and barely noticeable.

How accurate is the result?

Manufacturers of pregnancy tests provide a guarantee of results from 95 to 100%. But the possibility of error still exists. To be sure of the results, it is best to do several tests with a difference of 2-3 days.

There are situations when the presence of an interesting position is recognized, but in fact there is none, or vice versa. There are several reasons for this.

A false negative result occurs in the following cases:

• drinking plenty of water before testing;
• heart or kidney disease;
• gestation period 1-2 weeks;
• pregnancy pathologies;
• the girl takes medications containing hormones;
• recent abortion or loss of a child.

A positive result in the absence of pregnancy occurs for the following reasons:

• urine for analysis is not fresh or testing is not carried out in the morning;
• diseases of the female genital organs;
• non-compliance with instructions for use;
• poor quality test;
• menopause

In order for the test result to be as correct as possible, be sure to check the integrity of the packaging, the expiration date of the device, carry out the procedure in the morning and at least 7 days after the planned date of the start of menstruation, and also repeat the process after 2-3 days.

Examination by a gynecologist

This method cannot be considered an early diagnosis. A gynecologist can determine pregnancy with a higher degree of probability at a period of 7-8 weeks, although an experienced specialist can do this even at a period of 5 weeks.

From the moment the embryo develops, changes in the organs of the woman’s reproductive and reproductive systems are noted:

• The increased blood flow gives a bluish appearance to the external genitalia, vaginal walls and cervix - the doctor determines this during a visual examination.
• The structure, size and shape of the uterus change - it becomes round and soft.
• In some pregnant women, the uterus deviates forward , and a thickening resembling a ridge appears on its surface (Henter's symptom).

To confirm his suspicions, the gynecologist will definitely prescribe a blood test for the presence of the pregnancy hormone and an ultrasound scan - these methods are considered the most reliable and make it possible to determine pregnancy with a probability of up to 98-99%.

When can it be done?

When to do a jet test to determine pregnancy, the woman decides for herself. But at the same time, you need to take into account the period during which the device will show the most accurate result. The moment when you need to do a rapid test depends on the regularity of the menstrual cycle. After possible ovulation, a woman must count the appropriate number of days - at least 10.

If you plan to do a test after a delay, then diagnostics can be carried out on any day and at any time of the day. Even on the first day of the delay, provided the woman has a regular cycle, the inkjet test system will accurately determine the presence of pregnancy.

But few women can wait until day X - the first day of no period. Many people want to know the result as early as possible. A highly sensitive rapid jet test will help with this. But a mistake cannot be ruled out.

It is important to determine which day is best to conduct the study so that its reliability is high. Of course, these should not be the first days after the intended conception. You can start diagnosing a few days before the start of your period, but not earlier.

What to look for when choosing

The criteria for choosing a high-quality test will help you purchase an effective and worthwhile device that determines pregnancy or its absence.

• Place of determination. Not all tests are used in any location without urine collection. Jet tests must be placed in a container with urine and wait 3-5 minutes. When collection is not possible, then purchase a tablet test, which is easy to perform both at work and in the shopping center.
• Deadlines. After ovulation has passed a week or less, and you can’t wait to see 2 stripes, purchase tests with a visibility of 10 mIU/ml. Such devices can show results 5 days before the expected menstruation.
• Determination accuracy. Today, electronic tests that show either plus, minus, or weeks are considered the most accurate. The visibility of mIU/ml is not written on the packages of such tests, but there is information on the Internet that states sensitivity over 30 mIU. However, this statement is incorrect. Electronic tests have the highest visibility and determine pregnancy or lack thereof accurately and with certainty.

How does it work?

The principle of operation of absolutely all tests is the same: they help determine whether the girl’s body contains the hormone hCG (human chorionic gonadotropin), which appears in the blood as soon as the embryo attaches to the cavity of the uterine wall.

All tests can give accurate readings only some time after the delay, because hCG is not immediately observed in the woman’s urine.

The only way to find out if pregnancy has actually occurred is to take venous blood. Of course, with the help of this analysis, you can find out about the occurrence of conception much earlier (about 5 days) than by taking a test. In high-quality and expensive products, the strip has a high level of sensitivity, so the result will be accurate.

Express test indicators start at 25 mUI hCG. According to frequent statements by experts, sensitivity, which can be indicated with even more accurate data (10 mUI hCG), is simply a ploy by developers to increase sales. Also, it is worth remembering that it is impossible to determine pregnancy before the delay using such a means, because the amount of chorion in the urine and blood is negligible.

Conception occurs on the day of ovulation, so the test is recommended 12 days later

Instructions

Let's look at how to properly use tests from different manufacturers.

Evitest inkjet pregnancy test

The Evitest Perfect inkjet test cassette determines the presence of pregnancy with an accuracy of over 98%. But it is recommended to carry out diagnosis no earlier than the first day of a missed period.

According to the instructions, the Evitest Perfect jet pregnancy test is used in the following way:

• open the package, remove the cassette, remove the protective cap from the device;
• place the tip of the test system, marked with an arrow, under a stream of urine for a few seconds (no more than 10), then close it again with the cap;
• within 5 minutes expect the result - one or two pink stripes.

Clearblue Compact test

A classic inkjet test in a thin body similar to a ballpoint pen. Rapid test manufacturer Clearblue is considered the best in its niche.

Key points on using the device:

• the test must be used once immediately after opening;
• place the test tip under stream of urine for 3-10 seconds;
• remove the device no later than 10 seconds, close with the protective cap;
• evaluate the result of the study in 5-10 minutes;
• assessment of the result: two blue stripes - there is pregnancy, one stripe - there is no pregnancy, if there are no stripes - the test is defective or the study was performed incorrectly.

Clearblue Plus test

The device has an ergonomic design, and with the help of a wide tip and curved handle, inconvenience and errors when using the test will be minimal. It is recommended to carry out diagnostics with this jet test from the first day of a missed period or starting 4 days before their start. The sensitivity of the device is 99%. The accuracy depends on the day of the test: the earlier, the lower the sensitivity will be.

Rules of use:

• open the package and use the test immediately;
• place the tip of the device for 5-6 seconds under a stream of urine, and it should instantly change its color to pink;
• place the test system on a flat surface, evaluate the result after 3, but no later than 10 minutes;
• the result in the form of “+” and “-” signs will appear in the test window.

Clearblue Digital

This test from Clearblue simultaneously performs two tasks: it determines the presence of pregnancy and determines its duration in weeks. The sensitivity of the device is more than 99%. You can start diagnosing 5 days before the expected start of your period.

Rules of application:

• remove the device from the packaging and remove the protective cap;
• place the test tip under stream of urine for 5 seconds;
• close the tip with the cap, place the device horizontally and wait for the result on the screen, while the indicator of the device should work;
• after a few minutes, the result of the study will appear on the screen: the signs “+” or “-”, if the result is positive - weeks from conception.

Frautest

Frautest Comfort is an inkjet test system with high accuracy and sensitivity. Its use is practically no different from the use of other jet tests: the device is removed from the packaging, the receiving tip is placed under a stream of urine, and the result is assessed after a few minutes.

Tests made in Russia

Among the pregnancy tests produced by Russian manufacturers are:

• highly sensitive Insure test (12.5 mIU/ml), available in the form of test strips and tablets;
• Rest assured test (25 mIU/ml), available in strip form;
• “I was born” pregnancy tests are available with a sensitivity of 12.5 mIU/ml in the form of test strips and inkjet test cassettes.

How often do tests make mistakes, and at what stage do they not show a pregnancy?

A negative result instead of a positive one may appear if you performed the procedure earlier than the peak concentration of the gonadotropin hormone.

Don't forget that the test can also be wrong.

At the time of testing, it was simply within the maximum permissible limit for non-pregnant women, so it did not determine your new position. Repeat the test in a few days.

HCG level in urine

In a non-pregnant state, the level of hCG in the blood does not exceed 2-3 IU. In urine this amount is even less. Immediately after implantation, which occurs 3-7 days after the release of the egg, the amount of the pregnancy indicator begins to increase. Every day it increases by 1.5-2 times. How many days after conception will the test show pregnancy? A table of the norm of hCG in urine will help to determine approximately.

In this table you can see what the content of hCG is in the urine by day from conception.

You should take into account the fact that the moment of sexual intercourse does not always coincide with ovulation. Sperm can exist in a woman’s body for up to 7 days. For this reason, it is necessary to count from the day the egg leaves the ovary. You can reliably determine the moment of ovulation using appropriate tests, measuring basal temperature or ultrasound.

Comparative table of the presented tests

In order to compare the presented products, we recommend taking a look at the table with their characteristics below.

Why is early pregnancy diagnosis necessary?

The content of the article

Pregnancy is an important moment for every woman. And even though the news that a small life is already developing inside brings true happiness to some, and causes panic and fear for others, you always want to know about it as early as possible.

Early diagnosis will help:

• Decide.
  If you plan to continue your pregnancy, it is very important to take all tests on time and calculate the possible risks of pathologies in the fetus. In the early stages, a woman has the choice to continue pregnancy or stop.
• Do no harm.
  In the early stages of pregnancy, the embryo is extremely vulnerable. Often expectant mothers take strong medications and continue to smoke only because they do not know that a new life has already begun.
• Do not tighten.
  If pregnancy is not desired, abortion should be done as early as 6 weeks. During this period, you can do without surgical intervention - the gynecologist will recommend medical termination of pregnancy (abortion with pills) or, if there are contraindications, vacuum abortion.

How did you find out about the fact of conception before, without doctors?

In times of lack of modern facilities like tests and examinations, people relied on folk remedies to determine whether a girl was pregnant. The methods made it possible to determine pregnancy at home even before detecting a delay.

By observing several generations of women, it was possible to identify the following methods that reveal that a girl is pregnant:

1. Determine by the state of urine. It was boiled in a metal container, then poured into a glass container. If a precipitate is observed, white flakes appear, it is assumed that conception has occurred. Another option for understanding that a girl is pregnant without a urine test was used in the Middle Ages. Red wine was mixed with it. Cloudy urine indicates a negative test result. If there were no changes and the urine was clear, it was concluded that there was pregnancy.
2. A popular method was using a ring, which was tied to one’s own lock of hair and hung over the stomach. When it continues to hang motionless, it means there is no fruit. If it starts to move and spin, the result is positive.
3. The method of how to find out that a girl is pregnant without a test was in the old days based on the opinion that such a situation changes female energy. They took glasses. On one they wrote “pregnant”, on the second “not pregnant”. Then they planted onions in them and observed where the shoots would previously grow to 4 cm. But this method takes a lot of time.
4. Relied on dreams to determine pregnancy at home. When a married girl saw water or fish in a dream, it was assumed that conception had occurred.
5. Taste preferences will help determine pregnancy at home. The expression “craving something salty” is an ancient sign indicating an imminent replenishment. This bias can be scientifically substantiated. The water-salt balance of a pregnant woman changes, and there are not enough microelements. This is how the woman’s body tries to replenish previously lost sodium.
6. There is another way to understand that you are pregnant without a test. It originates in Ancient Egypt. This is how the presence of a fetus and its gender were determined. A woman urinated on wheat and barley seeds for a couple of days. If the first seeds germinate, a girl will appear. If the barley sprouted, then they expected a boy. The absence of changes indicated that there was no fetus.

After fertilization, active restructuring of the female body begins.

During repeated pregnancy, many people easily determine its presence at the beginning.

The listed methods, used before the advent of modern methods, cannot be considered completely reliable. But often their results turned out to be correct.

How to determine pregnancy without a test: false pregnancy symptoms

Sometimes the presence of certain suitable signs is not a reason to contact a gynecologist, since these may be influenced by external or internal factors not related to conception. For example, changes in the composition of urine can also be caused by infectious processes in the kidneys, diarrhea, or the predominance of vegetables in the diet, and not the first sign of pregnancy.

But the delay may be caused by:

• nervous tension or stress;
• a long, tiring road or a change in climatic conditions;
• diseases of the genitourinary system and other diseases;
• taking antibiotics and hormonal drugs;
• heavy physical activity (training, work);
• strict diet or sudden weight loss.

All this should be taken into account and excluded in order to prevent misdiagnosis in determining pregnancy.

Nerves and stress can cause a false sign of pregnancy - delay

Abnormalities in pregnancy tests

Blood test for β-hCG is prescribed to establish the very fact of pregnancy, identify ectopic, frozen, multiple types of pregnancy, and diagnose fetal malformations.

A blood test for hCG is very accurate: the concentration of the hormone is determined by a modern radioimmunological method. This parameter is important for the gynecologist, since in the presence of certain pathologies the hCG level deviates from the norm.

An increase in β-hCG in the blood can be observed if:

• Multiple pregnancy.
• Anomalies of fetal development (for example, Down syndrome);
• Various trophoblast tumors (hydatidiform mole, choriocarcinoma).
• Tumors of the embryonic rudiment (this may include testicular or ovarian teratoma, seminoma);
• Diabetes.
• Toxicosis.

The hormone level decreases when:

• Frozen or ectopic pregnancy.
• Threatened miscarriage.
• Pathologies of fetal development (Edwards syndrome, etc.).

How to test for hCG

To determine pregnancy, a woman's blood is taken, and then based on the hormone content in it, pregnancy can be diagnosed and even the due date can be determined.

You should donate venous blood for the presence of a hormone-protein in the morning of the 3-5th day after a missed period. To ensure the results are as accurate as possible, contact a clinic with a good laboratory.

There are also certain conditions that must be met in order not to distort the results of the analysis:

• Blood is taken 5 hours after the last meal or in the morning on an empty stomach.
• The doctor taking the tests must be notified about taking any medications in order to take into account the substances they contain in the analysis.
• The doctor must be aware of the patients' diseases (if any).

This will help eliminate the factor of a false-positive increase in the level of the hormone in the blood, which can be caused by a number of reasons, ranging from diet to medication. To be more sure, you need to repeat the procedure after a few days.

It should be added that sometimes a blood test for the presence of the hCG hormone is prescribed to women and even men during a medical examination, because it may also indicate the development of oncology or hydatidiform mole. But in this case, the level of the hormone will in any case be less than the norm characteristic of a developing pregnancy.
