At what stage can you find out that you are pregnant? Earliest time to determine pregnancy

Many women who have reason to suspect that they find themselves in an interesting position ask a painful question: is it really yes or no? How can we accurately and, most importantly, quickly establish this exciting fact? On what specific day after possible conception can you solve this riddle? They listen to themselves, their body, their well-being every day and hourly - and from every little thing they make certain assumptions and conclusions. However, you need to know that at the very beginning of pregnancy, significant changes are practically absent, or simply unnoticeable, or well hidden. Only in some cases can this be determined directly after a few days, and in rare cases it is generally recognized only by an enlarged abdomen.

Definition of pregnancy

It can be established according to several main signs.

• Firstly, a delay in menstruation is the main sign of pregnancy. By this sign, pregnancy is determined almost unmistakably, especially if a woman has a regular menstrual cycle. But still, some women sometimes experience problems heavy bleeding, which usually go away quickly.
• Secondly, before the onset of menstruation at the usual time, a woman experiences cramps and pain, which are accompanied by a slight so-called implantation bleeding. This is also considered one of the early signs of pregnancy. The described symptom usually appears 6-10 days after conception. This is caused by the fact that the embryo attaches to the wall of the uterus - after which menstruation disappears.
• Thirdly, early pregnancy can cause headaches in a woman - this is caused by a radical restructuring hormonal levels hormones in a woman's body.
• Fourthly, a woman becomes lethargic, withdrawn, irritable, and has sudden mood swings. Many women have a sharper sense of smell, an improved appetite, and a craving for spicy, salty or sour foods. All these manifestations also relate to early sign pregnancy.
• Fifthly, many women experience painful manifestations in the breasts, its sensitivity increases, and pigmentation appears.
• Sixthly, some women begin to often run to the toilet “small times”, that is, they feel the need to frequent urination. This occurs because during pregnancy the uterus increases in size and at the same time puts pressure on the bladder.
• Seventhly, nausea may be added to all of the above symptoms. And this is the beginning of toxicosis, an indispensable attribute of pregnancy - by it you can almost unmistakably determine it. It usually begins in the second week after conception and ends around the thirteenth week. Types of toxicosis can be different: it can be simple malaise or severe nausea and vomiting, which dehydrate the body.

However, all of the above symptoms cannot be called absolutely reliable and indisputable for establishing pregnancy. They may appear as signs of other diseases.

What will the test show and when?

But is there a more accurate “determinant” of pregnancy in the early stages? There is, and it is very simple. This is a special pregnancy test - they are sold in all pharmacies. The accuracy of its results is 80-90%, but its results become correct only after 6-7 days from the day of conception.

Well, all your doubts will finally be dispelled only by a trip to the gynecologist, who, 3-4 weeks after the missed period, will reliably determine whether you are pregnant using an ultrasound examination.

Pregnancy is not a disease, and no pathological phenomena should be observed, which is why signs of pregnancy healthy woman almost impossible to detect immediately. However, every woman is concerned about how many days it will take to find out about pregnancy.

It is considered a delay in menstruation, but this is not entirely true sure sign, and that's why. Firstly, a delay in menstruation may be due to various reasons: due to changes in hormonal levels, due to inflammatory processes V genitourinary system, stressful situations or exacerbation of chronic diseases.

Of course, some women may develop toxicosis and nausea, but such phenomena are extremely rare. Basically, toxicosis begins no earlier than three to four weeks after conception, or even nine weeks.

How many days will it take to find out about pregnancy is of interest to many women, so they should know that the signs of pregnancy are different for each woman, and the symptoms do not coincide so often.

Whether you are pregnant or not will be shown by your body, you can recognize your “interesting” position by the breasts themselves enlarge (you will notice this by the bra, it just becomes tight), the veins become more pronounced.

If a woman notices that she has become more tired, even after minor housework, this is due to an increase in hormones in the blood at the beginning of pregnancy. This condition will be observed throughout the first trimester.

At the beginning of pregnancy, a woman also urinates more often, which causes her to wake up frequently at night. This is due to the fact that the woman’s body begins to intensively filter blood through the kidneys, and therefore such frequent urges appear.

At hormonal changes that occur during this period, a woman may develop headaches for no reason. They can also cause back pain.

How many days later can you find out about pregnancy? - this question is asked by a woman who longs to have a baby. Therefore, if a woman suddenly has an aversion to her favorite product or intolerance to smells that were previously pleasant to her, then this is the first sign of pregnancy and the onset of toxicosis.

A woman may also feel a sudden feeling of dizziness, which may increase in intensity and this can also be considered one of the first signs." interesting situation".

During pregnancy, especially in the first days, the temperature may rise, although this is not the main symptom. Nevertheless, basal temperature(temperature in the rectum) always rises, the main thing is to measure it correctly.

It should be noted that other signs of pregnancy may not appear in the early stages, but the “pregnancy hormone” can be detected in any case and in all pregnant women. How to find out if you are pregnant or not? It’s very simple, buy a test strip and check, this hormone can be determined by urine, but a more accurate determination of the hormone level is possible using a blood test.

May be a sign of pregnancy severe pain in the lower abdomen before the scheduled start of menstruation, but this does not indicate pathology, and such pain does not last long. Another sign of pregnancy is scanty spotting (a sign of attachment of the egg to the endometrium).

No one can say for sure how many days later you can find out about pregnancy, and this will not always be indicated by pain in the lower abdomen, headaches, nausea and vomiting. You should wait for the start of menstruation, and if you feel constant discomfort, you should consult a doctor and carry out a diagnosis, take tests to confirm or refute the fact of pregnancy.

To summarize, I would like to note that there are cases when the mother does not know about her situation quite a long period. Be attentive to yourself. We hope that the question of when you can find out about pregnancy has disappeared.

The most proven way to detect pregnancy is to take a blood test. Blood levels of certain hormones increase throughout pregnancy. This is one of the most reliable methods for determining a special situation.

But not every woman can conduct such an analysis, sometimes the reason is reluctance, sometimes there is simply no opportunity. And many simply do not see the point in spending money when there is an alternative way to resolve the issue.

How to easily detect pregnancy

The easiest way to check ( positive result)

The most accessible, simple way to determine pregnancy is a test. It can be bought at absolutely any pharmacy. The price range is huge. Often this is a small narrow strip that is treated with a special reagent.

This type of diagnosis is quite accurate. Many manufacturers claim that accuracy can be up to 99%. But it also depends on when you do the diagnostics. How many days after conception can a test show pregnancy? They write on the packages that starting from the first day of absence of menstruation, you can use the tester.

But many are beginning to feel internal changes even before the onset monthly cycle. Experts say that the accuracy of such methods depends on the time of application and there are strips that are more sensitive and others that are less sensitive. But if you do everything on time, almost any test will show the result.

You should not conduct research immediately after conception. The level of chorionic hormone, through which pregnancy is determined, will increase only after some time. Usually, a sufficient period is seven days for the test to show pregnancy, because many people are interested in the question of how many days after conception they can use it. Therefore, it is possible, but still not recommended, to use a test to determine pregnancy before a delay. This won't always be the case exact result(you need to be prepared for the fact that it will be false), but sometimes you can determine it in advance.

Positive and negative result

Ovulation occurs approximately halfway through the cycle. But fertilization may not occur on the same day, but within a week. And the hormone level will increase only on the fourteenth day after ovulation.

There is no point in using an ovulation test unless fertilization (fertilization occurs after conception!) occurred in the previous cycle. It lasts only 24 to 48 hours. During this period, the chances of getting pregnant are very high. When ovulation is over, the chances of getting pregnant are practically non-existent. The exception is late ovulation, before menstruation.

In the absence of menstruation, a diagnosis must be made and if it shows a positive result, then pregnancy has been determined. If negative, it is worth repeating the procedure after some time to exclude a false result.

Home diagnostic methods

Tablet version of the test

Now there are many ways to determine your condition yourself at home, which will help detect pregnancy within a couple of days after ovulation using a test. On the shelves of pharmacies we can see several types of tests:

• strip test, waiting for a reaction from three to five minutes;
• tablet, reactions in five minutes;
• inkjet, a couple of seconds is enough;
• digital or electronic, operates on the inkjet principle.

It is convenient because there is no point in looking out for the appearance of a strip. The result is shown on the screen.

Name	Description	Price	Accuracy (on a five-point scale, depending on the period)
Babycheck	A strip for lowering a container with urine. Susceptibility from 25 mME/ml	From 10 to 100 rubles	3
Evitest Proof	A device with a special window into which you need to add a few drops of urine. Susceptibility from 10-25 mME/ml.	from 50 to 150 rubles	4
Frautest COMFORT	Without the need to collect urine into a reservoir, the method of application follows from the name. The most convenient way to determine the state of pregnancy is several days late. Susceptibility 10 mME/ml	from 150 to 250 rubles	5

Before you check. Check the expiration date of the product. How smaller number sensitivity, the more accurate diagnosis is possible in the early stages.

Timing of determination after implantation

How many days can it take to take a pregnancy test after implantation? Devices that have a sensitivity of 10 mU/ml can be used to detect pregnancy from the seventh to tenth day after conception or implantation. Therefore, it is pointless to conduct tests before this date. Even the most sensitive can give false positive or negative results before the delay. Because the required level of hCG (the human gene used to determine pregnancy) will not reach required level. In order not to torture yourself in vain, the test should be carried out ten days after menstruation has not arrived. Or in two days, then for confirmation after some time.

The process of conception goes something like this

The optimal days to do the test after implantation depend on:

• how sensitive and high quality the tester is;
• what is the condition. When there is a threat of miscarriage, hormones are produced more slowly compared to a normal pregnancy;
• correct execution. You must do everything as written, according to the instructions.

If the results are negative, but menstruation still has not begun, it is worth repeating the procedure.

Operating principle of the tester

Sets the level of hCG in urine

All pregnancy tests work on the same principle. They determine the level of hCG in the urine. This hormone begins to be produced when the placenta develops. In women, under normal conditions, it is normal – it is from 0 to 5 mU/ml. Starting from the first week of fertilization, the level of this hormone and its concentration increases.

Testers are divided into two types based on sensitivity:

• those that determine the concentration of hCG from 10 mU/ml. Such a specimen can determine the condition already five or seven days after fertilization;
• those that can determine the concentration from 25 mU/ml. They are the cheapest in the pharmacy and determine the condition for more later.

So the principle of operation.

1. They set the hCG level.
2. The determination is possible due to the fact that each tester has an antibody to hCG. When the level is sufficient, the antibodies react.
3. Red streaks appear during the reaction.
4. Can be determined before starting menstrual cycle, and than. After a delay, the result will be more accurate. But you can check and repeat.
5. The timing depends on the date of ovulation.

It is best to carry out a pregnancy test in the morning, then it will show the true result. Because urine is most concentrated in the morning.

When the second strip appears, the result is positive with high probability(approximately 99%). Faint stripe– is also considered a positive result, but the hCG level is still too weak.

In some cases, you can get a false positive result - this can happen due to taking certain medications or if there is a tumor.

New unused device

Sometimes it may be false negative result. It happens:

• when the hormone concentration has not yet reached the required level;
• in case of kidney dysfunction;
• Drank too much liquid before the test.

Correct use of instructions

The principle of the test, which will show whether you are pregnant or not, is very simple:

• you need to wait for a certain day (whether it is a delay or you have calculated certain days from the moment of ovulation);
• In the morning, collect urine in some container (the container must be clean);
• lower the test strip to a certain mark for a few seconds;
• then you need to wait for three to five minutes;
• place the strip on a clean surface;
• after ten minutes the test is invalid;
• one bright red stripe – negative;
• two bright red stripes – positive;
• other cases (when a strip appears, but the second one - the result is invalid, or when the second strip is barely noticeable, it is worth doing another test after a while).

Nowadays, the development of the medical industry and technology makes it possible to make accurate diagnostics and predictions regarding the state of human health. This fully applies to the course of pregnancy. If previously no one could predict the date of birth or the gender of the child, today it is quite possible normal phenomena. Today, even the duration of pregnancy can be determined in several ways and even without medical participation. Let's find out about this in detail.

Why do you need to know your gestational age?

If we talk about methods for determining the duration of pregnancy, some can be called not very accurate, but convenient and accessible to most women, while others, more accurate, require special diagnostic examinations.

All these methods for determining the period serve one purpose - competent monitoring of the course of pregnancy and fetal development. Knowing the exact number of weeks of pregnancy makes it possible to timely diagnose developmental pathologies of the unborn child (for example, Down syndrome), deviations from the norm, and accurately determine the date of future birth. When the doctor knows the gestational age, then using ultrasound it is possible to compare generally accepted indicators and characteristics of fetal development with specific pregnancy. So, let's look at ways to determine the duration of pregnancy with their advantages and disadvantages.

How to determine the gestational age by the date of conception?

Conceiving a child is the fusion of an egg and a sperm, which occurs within a day or two after ovulation. Some ladies feel it based on certain symptoms, others purchase special tests to identify it, and still others measure theirs for this purpose. Therefore, it is easiest for the category of women who feel the onset of ovulation and know the day of conception to independently determine the duration of pregnancy.

But even if you accurately calculate the day of conception (if sexual intercourse was only once), gynecologists, for a number of reasons, put the gestational age at 2 weeks longer. Pregnant women consider this a sign of carrying a large child. Unfortunately, in the first weeks the size of the embryos is almost the same. Doctors simply state the gestational age. It is used to calculate the date of future birth. Therefore, knowing your gestational age by the day of conception is interesting for the pregnant woman herself, and not for her doctor.

By the way, some expectant mothers keep their due date calendar until the end of pregnancy. Then it will be simply interesting to compare it and the doctor’s term, to determine whose was more accurate.

The first movement of the unborn child is important parameter the course of pregnancy. After all, doctors, as a rule, write down future date birth depending on ultrasound readings in the first trimester and the day of the baby. Women giving birth for the first time feel such movements at the twentieth week of pregnancy, and multiparous women a little earlier - at 18 weeks.

How do doctors determine the gestational age?

When a pregnant woman comes to antenatal clinic for the first time, the gynecologist necessarily examines her on the chair. Gynecological examination helps in identifying existing problems and determining the duration of pregnancy. Good doctors They can quite accurately (with an accuracy of up to half a week), as well as the location of the fetus (meaning its likely location outside the uterus).

You should know that gynecological examination A pregnant woman with a delay of 3-4 weeks, that is, at a period of 5-6 weeks, notices a slightly enlarged uterus. Its size is approximately the same as chicken egg. And at 8 weeks the uterus is the size of a goose egg. Approximately the size of a woman's fist, she is the size of 10 weeks pregnant. Without any problems, the gynecologist determines the size of the uterus after 12-14 weeks of pregnancy. We are talking about the length of the uterus when examining a pregnant woman on the couch. In this case, the doctor uses a measuring tape.

How to determine the gestational age from the last menstruation?

Determining the duration of pregnancy by menstruation is called the obstetric period. How is it calculated?

This is not difficult, because the date of ovulation in this case is not taken into account. The duration of menstruation itself is not important. The doctor needs to know the date of the first day last menstrual period pregnant woman. It is from this day that the doctor begins to calculate the gestational age. That is, if you went to the antenatal clinic one week after the delay and are absolutely sure that your pregnancy is 3 weeks, then the gynecologist will give you a 5-week pregnancy.

How to determine the gestational age using ultrasound?

Traditionally the first ultrasonography a woman is prescribed at 12-14 weeks of pregnancy. But at this estimated time it is problematic to establish its accuracy. After all, the embryos of all expectant mothers develop equally only in the first weeks after conception. Then the doctor is able to determine the period with an accuracy of one day, and clarify the position of the child in the absence of a heartbeat. And if the ultrasound shows any abnormalities, then a repeat examination is prescribed after a week or ten days for precise definition deviations and exclusion of frozen pregnancy.

That is, it is possible to determine the gestational age by ultrasound only in the early stages. With two subsequent scheduled ultrasound doctors will set the gestational age in accordance with the parameters of the body parts of the unborn child, his head. However, we should not forget that the second half of pregnancy is a purely individual development kids. After all, the birth at term of girls and boys weighing 2800 g and 4000 g is considered normal.

At what date will an hCG test show pregnancy?

Recall that human chorionic gonadotropin (hCG) is one of the the most important indicators the presence of pregnancy, its normal development. HCG is a hormone that is produced in the body of a pregnant woman after implantation. ovum into the wall of the uterus, that is, after implantation of the embryo. This occurs already on the sixth to eighth day after fertilization of the female egg. It is the presence of this hormone in the blood and urine that is the basis for pregnancy testing. Traditional tests, which are sold at pharmacies, determine the presence of this hormone with two strips.

In the first trimester of pregnancy, this hormone stimulates the production of progesterone and estrogen. These two female hormone necessary to maintain the normal course of pregnancy.

You should know that in the first weeks the level of human chorionic gonadotropin doubles approximately every 2-3 days. An increase of 60 percent in two days is considered normal. As pregnancy progresses, the increase in hCG levels decreases. Namely, at 8-9 weeks of pregnancy, the level of human chorionic gonadotropin stops growing. On the contrary, it begins to decline at a slow pace.

By the way, when multiple pregnancy In women, the level of this hormone increases in accordance with the number of fetuses. That is, if there are three fetuses, then the hCG level is three times higher than normal. It is the standard, generally accepted norms of this hormone for different dates pregnancy are the main determinants of this period.

It should be taken into account that the gestational age is hCG level does not coincide with obstetric calculations. Why is this happening? The point is that according to human chorionic gonadotropin The gestational age is determined relative to the day the child is conceived. It essentially reflects the age of the unborn baby. And here obstetric term pregnancy is determined by the doctor regarding the date of the last menstruation and is not related to the period of conception of the child.

So, using the above methods you can accurately determine the gestational age. However, it is recommended to take into account that with the most correct calculations, your baby may be born earlier or later. That's why the main task expectant mother- to do everything in her power for a healthy pregnancy and the safe birth of a daughter or son.
