When a pregnancy test shows the correct result: a gynecologist's comment. How many days after conception a pregnancy test will show the exact result, how and when it can be done, calculator

18.09.2019

It happens that people want a child so much that the very next morning after intimacy with a partner they go to buy a test. A couple of decades ago, the fact of pregnancy was established by a gynecologist during an examination at week 10. This is a fairly significant period, because it involves a delay in menstruation. In addition to this, other signs will already have time to appear. Not all women know how many days to do a pregnancy test. In this article you will find the answer to this question.

Hormonal changes

When a woman has reached her goal, she managed to get pregnant, a special hormone hCG begins to be produced in the body. This substance is contained in a small amount in each of us, but its content can be accurately understood only after passing specific laboratory tests.

Upon the onset of conception, the level of the hCG hormone increases, preventing the ovulation process and providing the baby with proper growth and full development. It is possible to establish a high content of the hormonal component when taking urine for analysis. This is much easier to do at home. It is necessary to strictly follow the instructions.

Before hCG rises in the body of a future mother, a certain amount of time must pass. It is for these reasons that you should not rush to purchase the test and buy it the day after sexual contact. Otherwise it expects a false result and you will mess up the test.

Women are most likely to conceive during ovulation. If during this period there was unprotected sexual contact, then it makes sense to do a test. But you need to do this only after two weeks. If your cycle consists of 28 days, then after 14 days, it is just possible to detect the fact of successful fertilization. 24 hours after a successful conception, the concentration of hormones is still low.

It is possible to achieve plausible information within two weeks after ovulation. Many are wondering why a pregnancy test should not be done on the first day of delay? Often devices "deceive", therefore, ideally, it is better to do this on the third or fifth day.

How different tests work

The most popular devices presented on pharmacy shelves are tests with a sensitivity of 20-25 mIU / ml. However, the hormone will reach this level only two and a half weeks after conception.

When to take a pregnancy test after a delay? As already mentioned, it is better to wait three to five days. Early manipulations in most cases give implausible results.

You can do otherwise if you want to check beforehand. Ask your pharmacist for sensitive strips. They allow you to determine the fact of successful fertilization already on the seventh day after conception.

How many times you need to do a pregnancy test, the gynecologist finds out in each case, based on the data from the tests and the woman's survey.

The question of how many times a day you can do a pregnancy test arises if the result is confirmed. Usually one more time is enough for clarification and reassurance. However, this is not at all necessary; one use of a qualitative test is enough to have a reason to consult a doctor.

If the results are implausible, it is recommended to wait a couple of days for the hormone levels to increase, then repeat the test. In general, there are no restrictions on how often you can take a pregnancy test. You can purchase multiple devices and check multiple times.

Definition of pregnancy and irregular cycle

If the cycle is irregular, then you may have difficulty using strips to identify an interesting position. With an unstable schedule, it is difficult to establish the exact date of ovulation and good days for fertilization. It is difficult for you to determine when the next period will come.

The first symptoms will help in this matter, because the delay is far from the only guideline that can be relied upon in suspicion of pregnancy. If you notice characteristic manifestations behind you, then urgently go to the doctor, and he will help you find out the truth.

When is it appropriate to test

It doesn’t matter how the conception took place, it is recommended to carry out the test in the morning after waking up, without visiting the restroom. The level of hCG has become significantly higher, and therefore the results will be reliable.

Advertised newfangled tests do not bind to be checked at any particular time of the day. But, since we already know why a pregnancy test should be done in the morning, and we don’t want to get false results, we should not deviate from this rule, especially when it comes to early pregnancy.

Teas and diuretic drinks lead to frequent urination, which lowers hCG.

If you have been late for more than five days, then you can take the test at any time of the day. The content of the hormonal substance has already reached the level at which it is possible to accurately detect the onset of pregnancy using any test.

Checking while breastfeeding

It is quite difficult to detect the fact of pregnancy during breastfeeding. The situation is aggravated by the fact that at first you will not have a period. There is also a claim that hw affects the protection against unwanted pregnancies. But it is fundamentally wrong. The absence of menstruation does not indicate the absence of an ovulation period. So successful fertilization may well happen after one cycle. Often women get confused in these moments.

An express study during breastfeeding should be carried out every month until the cycle is restored. When menstruation resumes, the test should be carried out, as always, according to the standard scheme: a few days after the delay.

What are the types of tests

Today, there are several types of devices that help determine the fact of pregnancy. Regardless of the desire or unwillingness to have a child, a woman always wants to know about her condition. Innovative devices differ from each other in their functionality and other characteristics.

What are the most popular options:

The jet type shows a quick response, that is, its response to hCG is super sensitive. You can see the result within a minute.
The strip test is the most popular. This is a budget and very convenient option. The result can be seen already in the fifth minute of the test. But in no case should the device be overexposed or underexposed, otherwise the results will be implausible. Therefore, this method is considered uninformative.
Test tablet. This device provides detailed information about the condition of a woman. Usually it is used in hospitals, but if you have experience and opportunity, you can use it at home. Just put some urine on the tablet. When to take a pregnancy test after a delay using this device? You can use it even the next day after the delay.
The most financially costly digital test. This device does not give you a reason to doubt your position.

Each of these methods has its pros and cons. If you doubt the information content of the device, it would be wiser to contact your gynecologist at the antenatal clinic.

We suggest using the calculator online: when to take a pregnancy test after conception.

In what cases the device gives false results

The operation of various devices requires compliance with the principles of the instructions for use, therefore deviations in the information may occur. It also happens in certain conditions of a woman:

With an ectopic pregnancy, the results will be false.
In case of incorrect operation of the device, if it was used ahead of time.
If the test fails. Read the instructions, where the expiration date of a particular test should be indicated.
In case of improper use of the device, which can occur when the instructions are not carefully studied or ignored.
With an increased concentration of fluid in the urine, if the woman drank diuretics or drinks.

There are also implausible positive indicators that indicate pregnancy:

The remains of the fetal egg after abortions and interventions.
Taking certain hormonal medications.
The presence of malignant neoplasms.

If you have doubts about the reliability of the information received, then you should consult a doctor to find out the truth.

Artificial insemination

To conceive a child artificially, experts accurately set the day according to the schedule of menstruation and ovulation. In all other senses, this process is carried out in the same way as in natural sexual contact.

The study is performed after 17-18 days: approximately on the third day after the delay in menstruation.

If injections were introduced to activate hCG, it makes no sense to engage in checks immediately after the end of the course. The level of the hormone will be so high that even the most uninformative test will give a positive result.

For your own confidence and peace of mind, take the test after 15-17 days.

IVF and pregnancy check

After you have gone through the IVF procedure, you can do a pregnancy test two weeks later, not earlier. Even if the results do not meet the expectations and hopes for motherhood, do not be upset. Just buy a test in a few days, or donate blood for analysis at a medical facility.

How to check after an abortion

Often, women worry that the fetus has not been completely removed from the uterus. To calm down, test strips alone will not be enough.

Plausible results can be obtained within two to three weeks after the intervention. The hormonal background will already be stabilized.

The first manifestations of conception

As soon as all the studies are completed, you need to go to the antenatal clinic. The expectant mother can easily determine her interesting position by external criteria:

Sensitivity of the mammary glands and their enlargement.
The nipples become darker.
Lag is a classic indicator pointing to an interesting position.
Increase in basal body temperature.

Ultrasound pregnancy indicators:

Enlargement of the uterus.
A fertilized egg, which can be determined 14-21 days after conception.
Fetal heartbeat, which can be ascertained in the sixth week.
The movement of the child, which is visible on the monitor at a certain time.

Do not confuse other symptoms with signs of conception. Nervousness, apathy, dizziness, weight gain, nausea, frequent urination in a small way. All of these symptoms can be easily confusing, so it's important to see a doctor for a check-up.

Summing up

And in conclusion, I would like to say that all the indicated terms in this article are conditional, you do not need to try to calculate the time when you need to take the test with an accuracy of up to a minute. The period of ovulation often changes by itself due to stress, unusual physical activity, etc. Despite the fact that brands claim that their products give reliable results, you need to understand that this is just a publicity stunt.

In the life of every woman, sooner or later there comes a moment when she wants to give life to another person. It is generally accepted that it is possible to determine pregnancy only from the first day of the absence of menstruation, but is this true? After all, the expectant mother can not wait to find out if this long-awaited pregnancy has come?

Mom or not? Early pregnancy

For some women, this expectation becomes a miracle, and for some it turns into an overwhelming fear, so the possibility of diagnosing pregnancy in its early stages is always relevant. If the long-awaited miracle happened, what to do next?

For the expectant mother, the best option is to register with the clinic in the early stages of pregnancy. In this case, the probability of its successful course is much higher, because every day spent in the womb is important for the future child.

If pregnancy is unwanted for a woman, then an abortion should be done, as you know, in the early stages (from the first day of the delay and up to 10 days after it).

Is it possible to determine early pregnancy at all and how? At least once in her life, a woman asked herself these questions. And, of course, the answer was always the same: yes, it can be determined. And what should be done in this case?

The female body is a delicate and precise system that begins to change with the onset of the first day of pregnancy. It is these changes that can tell the expectant mother about the presence or absence of an “interesting position”.

Modifications in the work of the body after conception

The state of pregnancy is directly related to the course of the menstruation cycle, and this relationship is indicative for a woman. No wonder the cycle is counted from the first day of menstruation, since it is during this period that the birth of the egg occurs. Its development lasts from 14 (with a cycle of 28 days) to 17-18 days (with a cycle of 35 days), after which the adult egg is ready for fertilization.

With unprotected sex, conception occurs. A fertilized egg grows into the wall of the uterus and continues to actively develop.

Of course, these are far from all the preparatory processes for conception that occur in the female body. Against the background of the maturation of the egg, the endometrium softens, and the follicle, which reproduced the egg, transforms into a corpus luteum and begins to produce progesterone.

These internal changes affect the rectal temperature, which rises to 37 ° C, which is the most optimal body temperature for the development of pregnancy. The body in this state arrives within one week.

If the conception process did not occur, then everything returns to normal:

the yellow body stops its development;
exfoliated endometrium comes out along with menstruation;
rectal temperature drops.

The menstrual cycle starts over.

But what to do if fertilization did happen? The egg, fertilized by the most active sperm, continues its movement through the fallopian tube. Having not yet reached the womb of the uterus, the egg begins the process of division and development of the future fetus. Approximately 7 days later, the fetal egg autointruses into the uterus, after which the fetal membrane begins to actively produce the hormone chorionic gonadotropin, thanks to which conception can be diagnosed.

Pregnancy test or self-diagnosis

A 100% guarantee that a woman is pregnant can only be given by diagnostics in a medical institution, while blood is donated no earlier than a week (10 days) after the conception process itself.

Most often, a woman begins to suspect about her "interesting position" only when the delay in menstruation begins.

Pregnancy cannot be determined until the implantation of a fertilized egg into the wall of the uterus occurs.

Until its introduction into the uterus, the egg has no contact with the mother's body. That is, the female body itself is not yet aware of its own pregnancy, so no changes simply occur.

But constantly running to the doctors is far from the most suitable option. Today, more convenient methods for calculating pregnancy are available, including in the early stages and, of course, not without the help of the same chorionic gonadotropin (hCG hormone). Every woman can easily purchase a pregnancy test at a pharmacy. Between themselves, they may differ in appearance, color of packaging, price, but built on the same principle of action. The detection of pregnancy using a test occurs on the principle of detecting this very hCG hormone in the urine.

So from what day of conception is it possible to determine pregnancy by test?

Tests are usually designed to be performed on the first day of a missed period, but there are also tests with greater sensitivity (and therefore higher cost), which can detect pregnancy a few days before a missed period.

Of course, when choosing to determine pregnancy using a test, it is worth considering the possibility of error, before contacting a antenatal clinic, several tests should be done. There should be a short break of 2 days between procedures.

Pregnancy and basal temperature

In addition to a pregnancy test, you can use other methods for calculating an “interesting position”, for example, measuring rectal temperature. The procedure is not the most pleasant, but every woman can do it.

Measuring basal temperature is quite troublesome, but reliable, as it has been tested by more than one generation of women in labor. It is recommended to do this procedure before the start of pregnancy, that is, 2-3 months (60-90 days) before the expected date of conception, in order to identify the behavior of your own body. The measurement procedure is quite simple, but it must be done strictly following all the rules, otherwise the effectiveness of this method is reduced to zero.

Of course, this method should not be taken as a basis, but as an auxiliary tool in detecting pregnancy, rectal temperature measurement is suitable for absolutely all women. It should be remembered that the temperature rises only during ovulation, and falls after it ends. If the basal temperature remains elevated, you should immediately contact a gynecologist.

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 position.

But not every woman can conduct such an analysis, sometimes the reason is unwillingness, sometimes there is simply no way. 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 affordable, easiest 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 processed 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? On the packages they write that starting from the first day of the absence of menstruation, you can use the tester.

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

Do not conduct research immediately after conception. The level of chorionic hormone, due to which pregnancy is determined, will only grow after a while. Usually a sufficient period is seven days for the test to show pregnancy, because many are interested in the question - how many days can they be used after conception. Therefore, it is possible, but still not recommended, to use a test to determine pregnancy before a delay. This will not always be the exact result (you need to be prepared for the fact that it will be false), but sometimes you can determine in advance.

Positive and negative result

Ovulation occurs around the middle of the cycle. But fertilization can occur not on the same day, but even during the week. And the level of the hormone will increase only on the fourteenth day after ovulation.

It makes no sense to use the test during ovulation, unless fertilization (fertilization occurs after conception!) Has occurred in the last 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 virtually non-existent. The exception is late ovulation, before menstruation.

In the absence of menstruation, it is necessary to make a diagnosis, and if it shows a positive result, then pregnancy has been determined. If negative, it is worth repeating the procedure after a while, to exclude a false result.

Home diagnostic methods

Tablet version of the test

Now there are many ways to determine your condition on your own at home, which will help detect pregnancy in a couple of days after ovulation using the 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 after five minutes;
jet, a couple of seconds is enough;
digital or electronic, operates on the principle of inkjet.

It is convenient because it makes no sense to look 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 term)
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 draw urine into the tank, the method of application comes from the name. The most convenient way to determine the state of pregnancy with a few days of delay. Susceptibility 10 mME/ml	from 150 to 250 rubles	5

Before checking. Check the expiration date of the product. The lower the sensitivity figure, the more accurate early diagnosis is possible.

Terms of determination after implantation

After how many days it is possible to do a pregnancy test after implantation. Devices that have a sensitivity of 10 mU / ml can be used to determine pregnancy from the seventh to the tenth day after conception or implantation. Therefore, before this period, it is pointless to conduct tests. Even the most sensitive can give false positives as well as negatives before the delay. Because the required level of hCG (human gene, pregnancy is determined with the help of this hormone) will not reach the required level. In order not to torment yourself in vain, the test must be carried out ten days after the menstruation has not come. Or two days later, then for confirmation after some time.

The process of conception goes something like this

The optimal days when you can do a 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, in relation to a normal pregnancy;
correct execution. It is necessary to do everything as written, according to the instructions.

If the results are negative, but menstruation still does not start, it is worth doing a second procedure.

How the tester works

Sets the level of hCG in the 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 distinguished by sensitivity into two types:

those that determine the concentration of hCG from 10 mU / ml. Such an instance can determine the state as early as five, seven days after fertilization;
those that can determine the concentration of 25 mU / ml. They are the cheapest in the pharmacy and determine the condition at a later date.

So the principle of work.

They set the hCG level.
The definition is possible due to the fact that each tester has an antibody to hCG. When the level is sufficient, the antibodies react.
During the reaction, red bands appear.
You can determine before the start of the menstrual cycle, and then. After a delay, the result will be more accurate. But you can check and repeat.
The duration depends on the timing of ovulation.

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

When the second strip appears, the result is positive with a high probability (about 99%). Weak line - 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 drugs or if there is a tumor.

New unused appliance

Sometimes there may be a false negative result. It happens:

when the concentration of the hormone has not yet reached the required level;
in violation of the kidneys;
Drinking too much liquid before the test.

Correct application of instructions

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

it is necessary 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 you collect urine in some container (the container must be clean);
lower the test strip to a certain mark for a few seconds;
then it is necessary to wait from three to five minutes;
place the strip on a clean surface;
then ten minutes the test is invalid;
one bright red stripe - negative;
two bright red stripes - positive;
other cases (when the strip appeared, but the second - the result is invalid, or, when the second strip is barely noticeable, it is worth doing another test after a while).

Almost every woman at some point in her life wonders about her condition - is she pregnant or is the delay associated with any abnormalities in the body? Pregnancy test - what day to do it? For some, this question is connected with a wonderful feeling of anticipation of alleged motherhood. Someone, on the contrary, expects only a negative answer.

What is conception? A female egg is fertilized. The emerging embryo is in the uterus, starting to produce hCG hormone. The hCG hormone is human chorionic gonadotropin.

For a long time, it was possible to determine pregnancy only by visiting a gynecologist. The gestation period could already be 2-3 months. Science does not stand still, diagnostic methods have changed, and you can get an answer to this question much earlier.

After how many days the test will show pregnancy when using regular strips

The modern way, which allows you to find out with a fairly high probability whether a woman is pregnant or not, is simple. it pregnancy test which can be purchased at every pharmacy. But the question often arises: after how many days the test will show pregnancy, if you count from the time of PA.

After how many days will the test show pregnancy using conventional strips that almost all modern women have used in their lives? As is known, in this case Analysis of urine. This method is good because it simple, no need to go anywhere, you are doing the test at home.

Every woman knows that there are practically seven days to conceive a child: five before ovulation and two after it. So what day to take a pregnancy test? Even having determined the exact time of ovulation (which is quite difficult to do), it is useless to test after a couple of days. Until the secretion of hCG has started, it is impossible to detect pregnancy.

Test makers say a woman can do it a day or two before the expected delay.

Only about 25% of women find out that they are pregnant two days before the expected menstruation.
In one day - about 40% of women hope to become future mothers.

Statistics give the following figures: on average, only in two weeks (13-14 days) women will be able to see two stripes on the test if conception has occurred. Those. the most likely result is manifested on the day of the delay of menstruation.

Why is this data provided here? Asking the question - on what day the test shows pregnancy - women cannot get an exact answer. A positive result can only appear three weeks after ovulation. If the issue is very important to you, then on the first day of the delay, do analysis for hCG. Then get 100% result.

Therefore, the question: “A pregnancy test - what day to do?”, - remains open. If you do it at the wrong time or not in accordance with the instructions, you can get a false negative result. The woman will consider herself not pregnant, and then this issue will be resolved positively. For some, this will be a moment of joy, but for others it will only bring grief.

On what day to do a pregnancy test - gynecologists still advise you to wait 3 weeks after ovulation. Then you can achieve 99% of the result. Only after such a period does the hCG level reach a concentration sufficient for analysis.

Blood test: what day the test shows pregnancy

In addition to such a test, there is another accurate way that allows a woman to find out about her pregnancy or her absence. It's special blood analysis. Here is a little background information on this pregnancy test.

On what day does the test show pregnancy with this method? The analysis can be carried out from the seventh day intended conception.
How long to wait for a pregnancy result with a blood test? The result will have to wait about a day.
Is it possible to determine the exact gestational age through a blood test? The presence of the hCG hormone is determined and exact date pregnancy. This pregnancy test will determine both the qualitative and quantitative indicator of hCG.
