What minimum time the test shows. Does the test always show pregnancy? Does the test before delay

22.07.2019

The most proven way to identify pregnancy is to pass the blood test. The blood level of certain hormones increases throughout the entire period of pregnancy. This is one of the most reliable methods for determining a special position.

But not every woman can carry out such an analysis, sometimes the reason is unwillingness, sometimes there is simply no possibility. And many simply do not see the point of spending money when there is an alternative way to solve the issue.

How to just reveal pregnancy

The easiest way to check (positive result)

The most affordable, easy way to determine pregnancy is a test. It can be bought in an absolutely any pharmacy. Price range is huge. Often it is a small narrow strip, which is processed by a special reagent.

This type of diagnosis is accurate enough. Many manufacturers argue that accuracy can be up to 99%. But it also depends on when in time you will do diagnosis. After some days after conception, the test can show pregnancy? On the packages they write that since the first day of lack of menstruation you can use the tester.

But many begin to feel internal changes before the occurrence of a monthly cycle. Specialists say that the accuracy of such methods depends on the time of holding and there are more sensitive strips, there is less. But if you do everything on time, the result will show almost any test.

It is not necessary to conduct research immediately after conception. The level of chorionic hormone, thanks to which the pregnancy is determined, will grow only after a while. Usually, a sufficient period is seven days for the test to show a pregnancy, because many are interested in the question - after how many days you can use after conception. Therefore, it is possible, but it is still not recommended to use a test to determine pregnancy before delay. It will not always be an accurate result (you need to be ready 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 not happen on the same day, but for a week. And the level of hormone will increase only by the fourteenth day after ovulation.

It makes no sense to use the test during ovulation, if only fertilization (fertilization occurs after conception!) It happened in the past cycle. It lasts only from 24 to 48 hours. During this period, the chances of pregnant are very high. When ovulation ended the chances of becoming pregnant practically absent. Exception - late ovulation, before month.

In the absence of menstruation, you need to do a diagnosis and if it shows a positive result - it means pregnancy managed to determine. With a negative one, it is worth repeating the procedure after another while, to eliminate the false result.

Home Diagnostic Methods

Tablet version test

Now there are many ways to determine their state of themselves at home that will help to identify pregnancy after a couple of days after ovulation by 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 in five minutes;
inkjet, enough couples seconds;
digital or electronic, acts on the principle of inkjet.

It is convenient because it makes no sense to look out for the appearance of the strip. The result is shown on the screen.

Name	Description	Cost	Accuracy (on a five-point scale, depending on the period)
BabyCheck.	Strip for lowering the container with urine. Perception of 25 MME / ML	From 10 to 100 rubles	3
EVITEST PROOF.	A device with a special window in which you need to add a few drops of urine. Perception of 10-25 MME / ML.	from 50 to 150 rubles	4
Frautest Comfort.	With the need to recruit urine into the tank, the use method comes from the name. The most convenient way to determine the condition of pregnancy in several days of delay. Exception 10 MME / ML	from 150 to 250 rubles	5

Before making check. Check the shelf life of the product. The smaller the sensitivity number, the more accurate in the early deadlines, diagnosis is possible.

Definition time after implantation

After some days it is possible to make a pregnancy test after implantation. Fixtures that have a sensitivity of 10 honey / ml using them can be determined by pregnancy already starting from the seventh to the tenth day after conception or implantation. Therefore, before this period, it is meaningless to carry out tests. Even the most sensitive can give false both positive and negative results before the delay. Because the level of hCG (human gene, the pregnancy is determined using this hormone) will not reach the required level. So that in vain does not torment the test you need to spend ten days after menstruation has not come. Or two days later, then to confirm after some time.

The process of conception runs about so

Optimal days when after implantation can be done test depend on:

how sensitive and high-quality tester;
what is the condition. When the threat of miscarriages occurs, the hormones are produced slower, in relation to normal pregnancy;
the correctness of execution. You must do everything as written, according to the instructions.

If the results are negative, but menstruation still did not start, it is worth a re-procedure.

Principle of work tester

Sets the level of HCG content in the urine

All pregnancy tests work according to a single principle. They set the level of HCG content in the urine. This hormone begins to be produced when the placenta develops. In women with normal condition, it is normal - it is from 0 to 5 honey / ml. Starting from the first week of fertilization, the level of this hormone and its concentration increases.

Testers are distinguished by the sensitivity of two types:

those that determine the concentration of HCG from 10 honey / ml. A similar instance can determine the state after five, seven days after fertilization;
those who can determine the concentration of 25 honey / ml. They are the cheapest in the pharmacy and determine the state at the later deadlines.

So the principle of operation.

They set the level of hCG.
The definition is possible due to the fact that each tester has an antibody to xg. When the level is sufficient, antibodies react.
With the reaction manifests red stripes.
It is possible to determine before the menstrual cycle, and then. After the delay, the result will be more accurate. But you can check and make repeated.
The deadline depends on the term of ovulation.

It is best to test the test for the definition of pregnancy in the morning, then he will show a truthful result. Because in the morning the urine is most concentrated.

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

In some cases, you can get a false positive result - this can happen due to the reception of certain drugs or if there is a tumor.

New unused device

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

when the hormone concentration has not yet reached the desired level;
in violation of the kidney work;
before the test, too much fluid is drunk.

Proper application of the instruction

The principle of action of the test, as a result of which you will show pregnant or not, very simple:

it is necessary to wait for a certain day (be it a delay or you counted certain days from the moment of ovulation);
in the morning you dial urine into some container (packaging should 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;
put the strip on the clean surface;
then ten minutes the test is invalid;
one bright - the red stripe is negative;
two bright - red stripes - positive;
the remaining cases (when the strip manifested itself, but the second is invalid, or when the second strip is barely noticeable, it is worth making another test, after a while).

In modern conditions, any woman can independently determine pregnancy without referring to the gynecologist.

For this, an express test is used. How is it arranged and what time is it recommended to conduct a study? This issue should be understood in detail.

Features of the work of pregnancy tests

The principle of operation of any devices for the diagnosis of an interesting position is the presence of simple indicators reacting with a hormonal substance - chorionic gonadotropin. HCG begins to rapidly produce when introducing a fetal egg in the uterus.

Several types of express tests are distinguished:

Test strip: For research, a strip marker is used containing impregnation zones. If the woman is pregnant, 2 strips will appear with the reagent interacting with the reagent, and if not - only one. To test, the device is lowered in Urin for 10 seconds, after which the result is 3-5 minutes.
Tablet test:a more complex device. It has a flat plastic box with small windows. One of them is a urinary, where urimin is introduced using a pipette, and the other shows the result of the analysis. After the placement of the biological fluid inside the tablet, the reagent is reactive and chorionic gonadotropin followed by colorless tissue.
Jet: This is an extended device with a foster end, where many microscopic tubules are located. On them urine flows into the device cassette, where the reagent is located. For testing, you do not need to prepare a special container. Submiss the receiving end to a stream of urin for a few seconds, and after 3-5 minutes, evaluate the reaction.
Digital Test: He has a display where the result is displayed. If the girl is pregnant, "Pregnant" will appear, and when there is no - "not pregnant". For testing, place the tip of the device in Urin and leave it for 3-5 seconds. Rate the result that appears on the screen.

The reagent for chorionic gonadotropin is applied to any type of tests. If a sufficient hormone content is present in the urine of a woman, a positive reaction will appear. Depending on the device, special designations arise: stripes, letters or signs. When hgch is not enough in the female organism or it is missing, a negative result will be revealed.

After how many days after sexual intercourse, the test shows the result

No matter how much I wanted to know, you are pregnant or not, you will have to gain patience and wait a bit. Chorionic gonadotropin begins to produce in the female organism after attaching the fetal egg to the wall of the uterus.

After unprotected sexual contact, fertilization occurs immediately: there must be 5-7 days. Consider that with the onset of the specified time the concentration of hCG in the urine is minimal, and the test will show a negative or doubtful result.

If you do not wait to get the result, tested immediately with the onset of the delay of the estimated menstruation.

How many times better to do research? Experts recommend purchasing 2-3 devices to accurately confirm pregnancy.

From what time the result will be as accurate as possible

Undoubtedly, you are interested in the question: how quickly a pregnancy can be diagnosed after unprotected pa?

Imagine that a woman has a standard cycle of 28 days. The ripe eggs will come out of the follicle for 14 days. When meeting a female genital cell with spermatozoom, conception comes. The fruit egg falls into the uterus cavity and is implanted on the fifth day into the wall of the uterus.

With the occurrence of pregnancy, if you count from the first day of the menstrual cycle, about 19 days from the date of the last menstruation begins to produce hCG. The concentration of hormone is doubled every day, and it will reach 32 MME / ml to 23-25.

The specified substance content will be just enough to accurately diagnose the "interesting position". A positive result will appear on the express test.

When a woman passes through the ECO procedure, the diagnosis of pregnancy is better to carry out no earlier than 2 weeks after the embryo substrate. In the case of successful transfer of the embryo, the device will show the cherished strips.

On what period of ectopic pregnancy test will show the result

With different pathologies of phallopy pipes, due to which the permeability is violated, there is a threat to the development of ectopic pregnancy. This state is when the fruit egg is attached to the wall of the pipe, cervical, ovary or to the abdominal organs.

Ultra-sensitive tests a week after implantation are capable of diagnosing fertilization. However, the device will appear on the instrument, the second lack of strip. Sometimes the analysis shows a negative result.

With ectopic pregnancy, there is a failure of admission to the urine of chorionic gonadotropin. Its content is not enough for normal reagent interaction. A few days later, when in the uterine pregnancy, the concentration of hCG in Urin should grow significantly, the express test will also show a fuzzy line without becoming more noticeable.

If you note that the dynamics of the study is abnormal, it is a reason for concern. Be sure to consult a doctor to sort out the situation and stop nervous.

The doctor will appoint blood test for hCG: in the early period of gestation, its content is above compared to urine. Also, the specialist will perform an ultrasound to confirm the pregnancy and determine the location of the crumbs.

When it is more likely to get an accurate result

Ovulation occurs approximately 2 weeks before menstruation. If conception occurred, after 5-7 days the fertilized egg is implanted in the uterus and begins to produce hCG. If calculated, the substance is produced by the day of the alleged menstruation. After introducing the concentration of chorionic gonadotropin every day increased by 2 times.

Suppose the fertilized egg attached to 7 days after ovulation, the hormone content increases to 2 MME / ml. The next day, the value of the substance rises to 4 MME / ml. By 9 day it will reach 8 MME / ml. Even ultra-sensitive tests are unlikely to diagnose pregnancy, as they detect hCG with a concentration of 10 MME / ml.

We continue counting. For 11 days, the CGH content will increase to 32 MME / ml, and all express tests can determine the conception. If ovulation has occurred later, the positive result will also get later.

On what day the analysis is made, depends on the very type of express test and quality:

when its sensitivity is 25-30 mm / ml, it is possible to check the pregnancy when the first day of menstruation delay comes;
if the sensitivity of the express test is higher and is 15-20 MME / ml, confirming fertilization is possible in two days before menstruation;
with a low threshold of sensitivity, the device determines the concentration of hCG in the urine in 10 MME / mg. Pregnancy is diagnosed 4 days before the estimated periods, however, the likelihood of obtaining a false result is high.

On the early period of gestation, the effectiveness of express tests ranges from 97 to 99%. In order not to get a negative or dubious reaction, manufacturers recommend always to test after a monthly delay. If you have purchased an inacid product, the procedure will be reliable in most cases.

A specialist tells about the timing and features:

Conclusion

When pregnancy proceeds without pathology, express tests determine its offensive correctly. Sometimes some women violate instructions for use and conduct diagnostics before the specified period, receiving erroneous results.

If you want to determine exactly if the conception occurred after unprotected sexual intercourse, make a study only with the onset of the delay of the proposed menstruation when the concentration of chorionic gonadotropin will increase to the required level.

When receiving repeated positive tests, be sure to consult a gynecologist to confirm pregnancy and register.

Pregnancy is an amazing period in the life of every woman when a new life is emerging in you and develops. Its offensive is always unexpected, even if the baby is waiting with impatience - not every ovulation is completed by the fertilization of the egg.

All women need to know from what time a pregnancy test shows, although there are disagreements about this. At first symptoms and new sensations you need to go to the pharmacy for the test.

But it is important to use it correctly so that there is no false result.

What is the action of tests?

Entering a sex life, each girl must have elementary knowledge about its reproductive system and how and when conception occurs. In many women's forums, one of the most popular topics remains "from what sentence a pregnancy test shows," which speaks of total ignorance. It would seem that the school was studied at the school, around us the mass of information on the "arrogant" topic, but there are obvious gaps in elementary knowledge.

To answer the question of what a minimum term shows a pregnancy test, it is important to understand how the test works and what reacts. How is the answer "binary friend of girls"? Why are two different tests tested in one morning give opposite answers? Who is to blame in the errors of the test strip? Let's deal with detail.

Buying a test in a pharmacy (or several indicators of different types), each of us hopes for an accurate answer. All of them have different sensitivity, respectively, different "truthfulness" on early. They can react as a sufficient concentration of "pregnant hormone" and on residual phenomena from the old fetus after an abortion or spontaneous miscarriage.

The indicator that reacts to the secretion of chorion (the forming placental envelope of the embryo) can also recognize other hormone substances. For example, the test does not distinguish with hormone-like molecules produced by oncological neoplasms. In this case, there is a weak strip. So sometimes a pregnancy test is mistaken, which shows a period of pregnancy in the form of numbers. But it is difficult to say without a full examination - this is an embryo or tumor.

Pharmacies offer a large assortment of tests of different manufacturers. But they are all classic or advanced variants of a simple Lacmus, known for school chemical experiments. Protein reagent is applied to different bases:

Paper.
Matrix.
Plastic window.

They have one goal - to identify the human chorionic gonadotropine molecules or hCG. But in the blood and urine in the first day after conception, there will be a low concentration of this substance. It depends on whether the ultra sensitive pregnancy pregnancy shows or is not able to reveal this hormone.

Each future mother has gradually increasing the level of this biological compound - from 0 to 10med / ml and higher. Starting from this level, the test system begins to recognize the release of chorion tissue, as soon as the fruit egg will fix in the uterine endometrium. Difference tests - in the verge of sensitivity to hCG, which is found in two ways:

with the help of laboratory analysis of blood (in the clinic);
with self-diagnosis, a pharmacy dough based on urine.

In any case, it is important to listen to other signals of your body to not be mistaken. But the final "verdict" will say a gynecologist, and not a test, no matter how "accurate", according to statistics and promises of the manufacturer on the packaging.

What time can you determine pregnancy

All hormones, in one or another concentration, are present in the blood and urine. The "hormone of pregnant" takes place filtering by the kidneys, like other connections, after that is derived from the body of a woman. Therefore, it is determined in the composition of urine, and its concentration does not "shivel". All tests work on the definition of this concentration.

Important: For most systems, the minimum threshold is unavailable, they can "try" hgch from 20med / ml, below - occasionally. Therefore, on an early period (before delay), ask only an ultra sensitive test for pregnant women in the pharmacy.

So what term does pregnancy test determines? As soon as the CCG concentration reaches a minimum sensitivity threshold - 10med / ml. After the fusion of the egg cell with a sperm on the journey of an actively growing embryo to the place of implantation in the uterus, about 1-2 weeks passes, then Chorion is actively developing and highlights its hormone.

If the fruit egg is stuck in the uterine pipes (this happens rarely), the hormonal background is uncertain. With ectopic pregnancy, the strip is weak or does not show pregnancy. But it is quite possible that everything is fine, the concentration of "control substance" is simply not high. There are doubts about checking for the "favorite doctor."

The journey time of the fruit egg in the uterus roughly coincides with the delay period. But the interval between the next menstruation in women (girls) is different - from 22 to 36 days. It is even more difficult to determine the deadlines when the monthly irregular, hormonal fot "jumps" and long fails to become pregnant. Therefore, it is not worth buying a test earlier than two weeks from ovulation (the outlet of a ripe egg from the follicle).

Attention: Well, when there are accurate data on ovulation days in your body. Therefore, it is important to celebrate cyclicity in a special calendar. These data will be suitable for both productive fertilization and natural protection.

What minimum time you can determine pregnancy? Most tests are still capable of issuing a reliable result in the threshold of a sensitivity of about 20 honey / ml (in urine and blood). This level concentration reaches approximately 12-14 days after fertilization.

So, if you expect menstruation, but it is not - buy a test and figure out the cause of the delay. You are lucky if you manage to buy an ultra sensitive electronic test, which will respond to the Pregnon mini-tabl (pregnant) or "Non Pregnon" (not pregnant) for 7-10 days. In any case, all pregnant women, with a gap in a few days, are again tested, buying different tests.

How to choose a suitable test?

Pregnancy tests offered in the pharmacy network are divided as far as species:

jet;
tablet;
strip strip;
electronic (digital).

The most affordable and popular - "striped friend of girls," they know about them. If you send your husband or a friend for a similar "device" in a pharmacy, for sure, he will buy the "two stripes". The most advanced husbands may ask the pharmacist "And what's the difference?" And listen to a small "sermon" about the most expensive and accurate tests. Most likely, in this case it will buy a digital, and not the cheapest - strip strip.

In order for such a test "inhapping," it needs to be omitted into the tank, where the morning urine is assembled - there is the highest concentration of hCG. The results will be in 5-10 minutes. If the dough next to the control strip did not appear the second, exactly the same in width and color - you are not pregnant.

What time can you learn about pregnancy with a striped dough? Unfortunately, they do not have great sensitivity. At best, during a delay or later, when the concentration of the control hormone will rise to the level above 20 honey / ml.

Tablet test is the very chain where you need to bury the urine (the pipette is attached). The sensitive reagent is in a special window, where and the control "dose" of urine should get. Chemical reaction occurs quite quickly. These tests are convenient and accurate, but the degree of sensitivity is approximately the same as a more primitive "extinct" analogue, the term of pregnancy "do not know".

Inkjet tests Experts are considered the most sensitive. It has nothing to do with inkjet printers or other devices. You just need to substitute for a fresh stream of urine.

Attention: if you see on their packaging the designation "10 honey / ml", know that this is a highly sensitive system. Their error is minimal, undoubted advantage - use in all conditions. What time can you learn a pregnancy? Before delay.

How to find out the term of pregnancy with the help of domestic test?

Electronic or digital tests are considered the most accurate, since they do not have phantom strips or other incomprehensible manifestations. If it recognizes pregnancy, the "+" or "pregnon" will be highlighted. No hCG in the urine - it will be written "Non Pregnon" or simply "-". The special indicator determines the concentration, respectively, will indicate the development of the fetus.

Important: Electronics with minimal pregnancy shows the result of such a test, but they are an order of magnitude more. Want to know the term pregnancy - clarify in a pharmacy that you need a test that reacts to the level of the concentration of chorionic gonadotropin.

When a pregnancy test shows an inaccurate result

Any test, even the most accurate, can be mistaken. According to research, most tests are reliable at 95-99%, and errors occur due to different reasons. For example, an overdue pregnancy test will show the correct result? Of course, no, no matter whether "2 strips" or "Non Pregnon" will show.

Often, the girls themselves are to blame for what they did not have what they had. There is a small chance to get a false answer in non-compliance with the recommendations. Do you read the instructions before applying? Most of the "weselves" fall into curious situations - dip the test case with the other side or substitute under the jet when it was necessary to bury the urine in the window.

Allocate two types of false responses of pregnancy test:

False positive.
False negative.

Strange, but some girls buy tests before an intimate date - it will be overdue if "this night" comes much later. Why during pregnancy test shows a negative result? For example, because it was used secondary or applied immediately after sexual intercourse. He is not designed for this.

When testing, it is preferable to apply the morning urine, it is useless to sleep until lunch, then go to the toilet, forgetting about checking. Then if the whole day there is watermelons and drink beer, strongly dilute the urine - as a result, "Non Pregnon" will be "non-pregnant.

When to go on ultrasound to determine pregnancy?

Registration in the female consultation is impossible with one "false" test, even if there are 2 or 3, and all positive. So when need to do ultrasound to determine pregnancy? When there are signs of pregnancy, confirmed by pharmacy test systems.

Most girls like fire are afraid of visits to the gynecologist. But, in any case, you will have to psychologically tune in to the fact that you have to get a "then the most" (hated) chair and undergo a visual inspection of the genitals, then go to ultrasound to determine pregnancy.

It will not cost to pass the smear and blood on hgch to the clinic laboratory. The blood test will show the answer 13-14 days after Pa, ultrasound is the final stage of confirmation of the fact of pregnancy. At the earlier, their accuracy is not more than 95%.

Be sure to be appointed and an ultrasound examination to determine the location of the fetus and its value. With a directed from the doctor, you can make a free ultrasound to determine pregnancy, if provided for in your area.

Important: The level of "pregnancy hormone" in the blood needs to be checked by an empty stomach, pre-stopping the reception of hormone-containing drugs or drugs with hormone-like compounds of plant origin.

What period of ultrasound determines pregnancy? From about the second month, but there are two types of ultrasound surveys:

Abdominal ultrasound (outer, the sensor is based on the stomach, the data is visible from the 5th week of pregnancy).
Transvaginal ultrasound The sensor head is introduced into the vagina (give more accurate data, starting from 2-3 weeks of dividing the fertilized egg).

Girls (women) became clear when to make the first ultrasound to determine pregnancy. But it is important to monitor your well-minded, to conduct a monthly calendar, where to celebrate the days of ovulation (middle cycle) to regulate the birth rate and plan a pregnancy.

Of course, the process of pregnancy is exciting for every woman. But a lot of stress brought the first weeks of waiting and a permanent question: I am pregnant or not.

In each cycle, a woman has only 6 days for the occurrence of pregnancy: 5 days before ovulation and 2 days after it. So how to find out what time you can determine your pregnancy? What methods of definition are available and are effective? I often ask such questions in the comments on the site, so I will tell you in detail.

Even if you are sure that in this cycle determined the term of ovulation and did everything for the fertilization of the egg, this does not mean that through a couple of days after the alleged conception, you need to go to the pharmacy for the test and the next day to the gynecologist with complaints of infertility. You can detect pregnancy after starting the secretion of the HCG (human chorionic gonadotropin), and this launch occurs not earlier than fixing the egg to the wall of the uterus.

After how many days after par, you can do a pregnancy test

There are 2 types of tests that will help determine whether to begin preparations for the emergence of a new family member.

Blood test

This method will help to quickly determine the pregnancy.

Positive moment: You can take blood already on July 7-12 after the alleged conception.

Negative moment: Testing takes about a day (the timing of obtaining the result varies, depending on the laboratory).

Usually define high-quality and quantitative hCG: the first will show the presence of this hormone in general, and the second indicator will indicate the exact number to determine the period.

In general, if you are pregnant, the blood test will show a positive result of 3-4 days after direct implantation or 9-10 day after fertilization and ovulation.

Analysis of urine

This test is easy to use and shows the result after 5 minutes. This is definitely a huge plus.

A minus such tests lies in the fact that they will not always show you a reliable result. Manufacturers argue that the test can be carried out 24-48 hours before the delay. But in fact, no more than 25% of pregnant women who have made a test for 2 days before the beginning of the alleged menstruation, received 2 stripes on it. Under the same conditions, 1 day before the delay, 40% of future mothers have confirmed their position with such a test. But still this amount is quite low. It turns out that women received not reliable information and could hope for her result.

On average, most women get a second strip on the test approximately after 2 weeks (by 13-14 days) after ovulation. Those. Just on the day of delay.

IMPORTANT! Despite the studies, there are cases that the test shows a positive result only 3 weeks after ovulation. We point out this data for the reason that the result on the delay day is negative and the woman is 100% confident, but it is necessary to double-check or pass the blood to the HCG.

Does tests always show the correct result?

Manufacturers indicate the packaging of home test for pregnancy. Efficiency equal to 99%. But this is far from that. All studies that confirm this number were carried out 3 weeks after ovulation, i.e. 7 days after the delay. But in the early stages, the test shows one strip, which knocks the future mom with a sense.

Learn the reasons why the most common test can be false positive can be.

But the causes of false negative test:

too early made a test;
the test came out of shelf life;
you do not follow instructions for use;
you do not use the morning urine.

What factors affect the test results

The term of implantation. Despite the fact that the test result depends on the presence of a pregnancy hormone (HCG), long-term implantation periods can lead to negative results, since the movement of the fertilized egg to the wall of the uterus takes about 7 days. Therefore, if you spend the test too early, be prepared to get a negative result.

HCG level in urine. The quantitative indicator may decrease if you drink too much fluid. In concentrated urine, the level of hCG is higher and the test result is accurate.

Sensitivity of home dough for pregnancy. Read the test instructions and compare the sensitivity of several products of this type: how it is more, the earlier, with greater accuracy you will learn the answer to your question.

The remaining methods for determining pregnancy

Basal temperature

Minuses: It is necessary to measure BT for 3-4 cycles, whether there is a more stable menstrual cycle.

pros: If you measure BT for several days after the delay, it will invariably will be higher than the norm - it will indicate a high probability of pregnancy, but it is necessary to take into account the "minuses" of this method.

Ultrasound

Minuses: At the first weeks of pregnancy, this study does not make sense, an ultrasound specialist is unlikely to see a fruit egg that is very small yet; In addition, I insist that it is impossible to bother at the stage of formation of the embryo, and it is only done on strict testimony of the attending physician.

pros: You can be sure that you have no ectopic pregnancy, and the presence of the second strip on the test is not a consequence of hormonal disorders.
