On which day of delay to do the test (on the first day of the delay)

When a woman dreams of a baby, it is difficult for her to control herself and calmly wait for a delay. The hand itself reaches for the dough on the pharmacy shelf. On what day of delay to do a pregnancy test is a completely non-idle question for the expectant mother.

How a pregnancy test works

Many girls would like to know when to take a pregnancy test after a delay. Is it possible to do testing on the very first day or is it worth waiting for a reliable result.

The main hormone that provokes the appearance of two cherished stripes is the hCG hormone. It ensures the vital activity of the fetus and does not allow it to die at the earliest stage of the gestation period.

HCG actively stimulates the development of the corpus luteum in the ovary, which produces another hormone important for maintaining pregnancy - progesterone.

Hormones take on the job of preparing the place for the fetus to anchor, supporting the growth of the endometrium. Blocks the release of new eggs and the onset of menstruation.

The concentration of this hormone in the blood and urine of expectant mothers increases day by day after fertilization and the appearance of an embryo.
Shortly before the upcoming birth, its level in the woman's body is significantly reduced.

Important! The later you diagnose after a delay, the more accurate the result will be.

All existing devices include certain reagents with antibodies to the pregnancy hormone.

1. Urine, getting on a special analyzer, interacts with them.
2. If the level of hCG in urine is high, two strips (indicators) are colored on the device - the result is positive. You can please the future dad and think about the name of the baby.

Important! If only one strip appears as a result, the test is negative. But you can rejoice: the controller is not overdue, as the only page informed you about.

Regular and irregular cycle testing

When conducting pregnancy tests, the fact of the regularity and irregularity of the cycle is of no small importance.

If the cycle is regular

If a woman has a regular cycle, then there are no problems with testing and determining pregnancy. The presence of ovulation for conception is an axiom of gynecology. It always takes place in the middle of the cycle and works perfectly on regular critical days.

1. Let's take a regular 30-day cycle as an example of analyzing the situation. Ovulation will occur in the middle, that is, on the 15th day.
2. A ripe egg, formed as a result of this process, remains in a state of full readiness for fertilization for 2 days.
3. When merging with the male reproductive cell, it forms a zygote, and slowly, for 5 days, moves to the uterus, where it must attach to the endometrium and begin its growth and development in a new capacity.
4. Plus 4 days to build up the hCG level in urine to a recognizable level.
5. Let's summarize all this data: (15 + 2 + 5 + 4) = 26. This means that a pregnancy test will determine the unique state of the female body for about 26 days.

In the blood, the indicators of gonadotropin are determined 4 days earlier and the accurate detection of pregnancy by blood on hCG is possible already on the 22nd day of the cycle or on the 23rd day of the cycle.

With a regular process, such a calculation is very easy to carry out using the formula:

BEFORE (day of ovulation - middle of the cycle) + 2 (egg lifespan) + 5 (for the journey to the endometrium of the uterus) + 4 (manifestation of hCG in urine).

And if the cycle is 28 days, all that remains is to plug in the numbers and calculate:

14 + 2 + 5 + 4 = 25 (a test check can be done on the 25th day of the cycle), or on the 21st day for a blood test.

Important! The probability of the reliability of the result is directly related to the susceptibility of the hormone to the reagent in the device. For the most truthful indicators, control should be done later than the calculated control dates.

If the cycle is irregular

If the cycle is not stable, things are a little more complicated. The best way to get the most accurate readings, and to determine on what day the test will show pregnancy delay, is to do more research.

1. You need to know the onset of ovulation, for this, use a tester similar to the one used for diagnosing pregnancy. Or conduct regular temperature monitoring.
2. When the date of release from the ovary of a cell ready for fertilization becomes clear, you can calculate the day of fertilization quite accurately. To do this, add 15 days to the time of ovulation.
3. If ovulation happened on March 4, after which unprotected intercourse occurred, we add 15, and we get that on March 19 it is already possible to carry out pregnancy testing.

How to test

Testing can show incorrect results if diagnosed in violation of the rules.

1. Morning urine contains the highest amount of hormones. The majority of women do not eat or drink at night. Therefore, in the morning, the largest amount of substances is collected in urine, by which one can judge the state of the human body.
2. Study the instructions on the package or in the insert, do not invent unnecessary diagnostic methods.
3. Pay attention to the storage conditions and periods indicated on the packaging.
4. Do not give in to curiosity and do not break the packaging until you are thinking of using the test.
5. Pay attention to the expiration date indicated on the packaging, an expired product will not give a true result.
6. Before and after testing, practice good hygiene: be sure to wash your hands.
7. Sticks and other devices with a reagent must be lowered into a container with urine exactly to the required level, and for the period of time that the manufacturer suggests.

How many days after the delay the test will tell the truth

Most pregnancy tests are carried out using modern technology, using highly sensitive reagents.

Almost all tests show the most realistic results on the first day of the delay.

By the supposed beginning of a new menstrual cycle, from the moment of the meeting of the female and male germ cells, it takes 12-14 days. And if pregnancy has come, then the level of gonadotropin in the morning urine by this period is already high enough to be determined by a sensitive test.

If the result is negative, it is better to do the diagnosis again after 2 days.

The test may not detect pregnancy on the first attempt for a number of objective reasons:

• ovulation passed a little later than the girl expected;
• errors in calculating the expected day of onset of bleeding;
• irregular cycle;
• low levels of hCG in urine;
• ectopic pregnancy.

If you have a 3 day delay, you did everything exactly as recommended during testing. the manufacturer, and the test shows only one strip, so with the thought of pregnancy this month, you will have to say goodbye.

This happens if a hormonal disruption occurs in a woman's body.

Is it worth testing a week after the intended conception

The pregnancy hormone, which all tests are focused on, appears in a woman's blood a day after conception. Its level for this period does not exceed five milli-international units per liter. In urine, gonadotropin can be detected only on the third day after its appearance in the blood.

Important! If the gestation period proceeds without pathologies, the level of chorionic gonadotropin rises rather quickly. The number of hormones can double in 2–3 days.

Pregnancy is an absolutely individual process. Whether or not the test determines the correct result depends on the internal characteristics of the female body.

There are many women in whom conception was confirmed even before the onset of menstruation, but no less than those women whose test showed a second strip only after a delay.

Sometimes on the Internet, on all sorts of forums, stories are heard how the test determined two bands the next day after being close with a partner. Such statements are classified as miracles or errors. Only when the amount of gonadotropin in morning urine increases to at least 10 units, pregnancy becomes visible for a highly sensitive test. These indicators correspond to a period of two weeks after ovulation. This is the first day of the next cycle.

Therefore, it is too early to carry out diagnostics immediately after possible fertilization. Although, if you want - why not! What if you have that very amazing case.

The problem is that tests that are done too early have two extremes: false positives and false negatives.

False negative result

It happens that the test fails and shows a negative result with the onset of pregnancy. This happens, but this is not always the fault of the device.

Why it is possible to get a false negative result is explained rather by the individual secrets of the female body than by a bad test.

1. Disorders from the endocrine system are possible: problems in the functioning of the thyroid gland, diabetes mellitus, metabolic disorders. All of these factors can have a negative impact on the appearance of the second streak.
2. There will be only one strip even with the existing threat of miscarriage.
3. Testing too early using a test of a low degree of sensitivity can also give a false negative result.

Some, especially impatient girls, start checking the results from day 21 of the cycle. If diagnosing is carried out long before the control date, on the 23rd day of the cycle or on the 20th day of the cycle, then even if you have it short and is only 21 days, then the level of hCG, even with a successful conception, will not yet grow enough to manifest itself on test.
There is nothing wrong with a girl checking the results every 2 days, just don't be discouraged. With such an early date, one streak is not yet a result.

Important! When choosing a pregnancy test, for early control, buy a test with a sensitivity not higher than 10-15 mMe.

False positive

If a false negative result is not alarming, then false positive results may indicate a health problem.

It is not so easy to emotionally accept that a positive indicator does not refer to a joyful event - the appearance of a baby, but to the disorders of your body.

1. Dysfunction of the ovaries or the formation of a tumor, which, like pregnancy, is capable of releasing hormones so that the female body does not reject it.
2. If a woman is being treated for infertility, then she should know that the hormonal drugs taken secrete the same hormones that come into contact with the reagents on the test, staining two strips.
3. After a poorly performed abortion, when fragments of biological material remained in the uterine cavity.

Pregnancy and pathology

Positive results can be indicators of serious pregnancy pathologies: an ectopic pregnancy or a frozen pregnancy.

Ectopic pregnancy

This pathology is characterized by the fact that the fetus begins to develop, attaching itself not to the endometrium in the uterus, but outside it, most often in the fallopian tube.

With further development and growth of the embryo, it can rupture the tube. It is dangerous for a woman's life. In this case, carefully look at how intensely the second stripe is colored.

The pale streak is also accompanied by additional symptoms: severe pain in the lower abdomen and bleeding.

With the combination of all these indicators, you must immediately seek medical help.

Frozen pregnancy

A pathology in which the fetus begins to develop, but then suddenly stops growing, freezes and dies. It is difficult to notice this pathology on your own without a doctor's supervision.

But you may be concerned about some signs: pain and sensitivity in the chest disappears, toxicosis abruptly stops. When conducting a repeated test, the pregnant woman notices that at the beginning there were bright, clear stripes, and then the second stripe completely disappears.

If there is a suspicion of a frozen pregnancy, repeat the test, and if there is no second strip, contact the antenatal clinic.

Varieties of tests

And yet, which test to choose in all that variety of choices so that it is the most accurate and convenient.

Consider the ranking of the most famous manufacturers of pregnancy tests for 2020.

According to the method of diagnosis, tests are divided into 4 groups:

• strip strips;
• inkjet;
• tablet;
• electronic.

Which one to choose is a matter of individual preference.

1. Strip strips are the easiest and most affordable option. The sensitivity of the strips can be from 10 to 25 units. According to the results of customer surveys, the best test in this category is: FRAUTEST express ultrasensitive - the average cost is 130 rubles. The sensitivity declared by the manufacturer is 15 mMe / ML. It can be used for diagnostics 2 days before the first day of the delay in the menstrual cycle.
