At what stage of pregnancy can the test already show 2 strips? If the cycle is 26-28 days, then can it show on the 25th day? and got the best answer

Answer from Cranberry Kislyukina[guru]
on average, tests show 10-14 days after fertilization, and the length of the cycle and the delay have nothing to do with it, it’s just that usually ovulation happens 14 days before the delay.
but everyone’s organisms are different and the amount of hormones is different, it shows someone only 4 weeks after the delay, and someone long before it.
the test showed me pregnancy 6 days before the delay, 7 days after conception.
so try it, if there are 2 strips, then congratulations, you need to make a couple more different ones to be sure, if there is one, then try later if your period does not start.
and it is not necessary to buy expensive tests, I have always used tests for 10 rubles, they never let me down.

Answer from Natalia Popova[active]
better after a day of delay try

Answer from ZLYUKA[guru]
if there is a delay a couple of days can and show

Answer from Ninon[active]
better buy 3 more tests, and do it on the fifth day of delay in the morning! and then there will be no doubts for sure! although I showed the delay on the third day! the main thing is to take tests different manufacturers and different prices!

Answer from Elena[guru]
from 1st day of delay

Answer from Maryska[guru]
test shows only after delay!! ! I usually take two different tests and do them in the morning on the first and second day of delay. the result has never failed

Answer from Caroline[expert]
Most home tests are sensitive from days 9 to 12 of fertilization.
Doing the test helps dispel doubts.
A blood serum pregnancy test (performed in the laboratory) allows you to detect pregnancy from 8 to 11 days of fertilization.

Maybe. But you don't have to :)

Answer from 3 answers[guru]

Any girl who wants to have a baby always wants to know if the cherished event has happened as early as possible. Fortunately, we live in the 21st century, and the arsenal of tools for early detection of pregnancy in modern medicine is already quite impressive. Impressive but imperfect: all diagnostic methods have limitations, and so far no way has been invented to check whether conception occurred immediately, a couple of hours or days after the act of love. But, fortunately, it won't take long to languish in anticipation.

About what is the earliest time when the conception that has occurred can be reliably judged, and on what day the pregnancy test will show positive result and will be discussed in this article.

Definition methods. How early can you find out about pregnancy?

All methods of early diagnosis of pregnancy can be divided into two groups: visual and laboratory.

The visual ones include ultrasound or an examination by a gynecologist in the chair, and the laboratory ones are the determination of the presence in the body of a special hormone, chorionic gonadotropin (usually abbreviated as hCG). There are two main ways to determine the level of hCG - by passing a blood test or by making a well-known home urinary pregnancy test.

Let's say right away that visual methods lag far behind the "chemical" methods in terms of the speed and accuracy of determining pregnancy. It is physically possible to see pregnancy on ultrasound only from the third week of embryonic development, and then only with sufficient qualifications of the doctor and high quality equipment, since. fertilized egg at this time only a few millimeters in size. Examination of a doctor in the chair is also subjective, since certain symptoms (softening of the cervix, a change in its shape) only indirectly indicate the patient's pregnant status.

In contrast, tests to determine the level of hCG can be used as early as a week after the onset of embryonic development and are free from uncertainty. An increase in the level of hCG (normally absent in a non-pregnant person) starts immediately after the fertilized egg attaches to the wall of the uterus, and serves as reliable evidence that the desired event has nevertheless occurred.

If you summarize the methods by which one is the most “fast”, you get something like this list:

1. Blood test for hCG.
2. Test strip (urine) for hCG.
3. ultrasound.
4. Visual examination by a doctor

And since we have an article about how to determine pregnancy as early as possible, below we will talk in more detail about the level of hCG in the body of a pregnant woman and about what day it is worth taking a pregnancy test or running to the laboratory to donate blood.

How does a pregnancy test work?

The principle of the pregnancy test is very simple - the reagents in the test strip change color if the level of human chorionic gonadotropin in the urine exceeds a certain level (this level is written on the test box; standard tests start showing a second strip from 25 units of hCG. There are also highly sensitive tests showing a second strip of hCG 10. However, only an increase in hCG to a level of 25 or more is considered worthy sure sign the onset of pregnancy, since lower levels may be due to simple physiological abnormalities).

On what day will a pregnancy test show a positive result?

Let's figure it out.

A positive result will appear only after reaching a certain level of hCG in the body, but how long does it take for hCG to become sufficient?

Most readers know that fertilization is possible only at the time of ovulation. However, after fertilization has occurred, a number of events must occur, requiring a certain period of time:

The period from the moment of fertilization to the moment when the test shows two strips is counted from the date of ovulation and consists of the period of several events:

1) Time for fertilization (up to 1 day)

2) Time to move from the fallopian tube to the uterus (up to 4 days)

3) Time for implantation (up to 4 days)

4) Time to produce enough hCG (up to 7 days).

First you need to determine when this cycle was ovulation. There are a lot of methods for determining it - from “folk” calendar ones to 100% accurate ultrasound. If you are not familiar with them, we advise you to read the article “How to “catch” ovulation”? All about the menstrual cycle by day.

Let's assume that you were able to calculate when this cycle was ovulating. What's next?

Not later than one day after leaving the ovary, the egg must be fertilized. We add 1 day to ovulation, we get 1 DPO (the day after ovulation) or the 15th day of the cycle (for a 28-day cycle).

3-4 days fertilized egg moves through the fallopian tube to the uterus. She enters the uterus at 5 DPO or day 19 of the cycle.

It takes 3-4 days for the embryo (in which at this point there are already about a hundred cells) to attach to the wall of the uterus. If everything went well, then at a maximum of 9 DPO or on the 23rd day of the cycle, the embryo will attach to the uterus (by the way, a number of pregnancies are interrupted already at this stage - if a normally fertilized egg simply could not attach to the uterine wall. This may be one of the reasons infertility . Therefore, girls who cannot get pregnant for a long time in the absence of problems with the cycle must definitely undergo a gynecologist check of the endometrium of the uterus).

So, after the embryo is attached, its outer shell (the chorion, which will later become the placenta) begins to secrete the treasured chorionic gonadotropin. It is this hormone that blocks the onset of the next period.

Before implantation, its amount is approximately 0-5 units. HCG level by day of pregnancy approximately doubles every day. That is, if on the first day after implantation it is equal to an average of two units, on the second day after implantation it will be equal to 4, on the third day after implantation it will be 8, on the fourth day 16, and, finally, on the 5th day after implantation it will exceed the threshold of 25 units and will be equal to 32 mIU /ml Recall that our implantation took place at 9 DPO (23 days of the cycle), add 5 days to this and we get that the desired concentration will be reached on the 14th day after ovulation or on the 28th day of the cycle (that is, 1 day before the start of the expected menstruation) .

But this is the concentration of the hormone in the blood! Desired concentration HCG in urine by day after implantation lags behind that in the blood by about 1-2 days. That is, the test will be positive for about 1-2 days of delayed menstruation.

But there are ways to “cheat” a little and find out information earlier. Here they are:

• Buy highly sensitive tests (look at the pharmacy box. It should indicate that the sensitivity of the test is not 25 mIU / ml, but, for example, 10 or 15).
• Collect more "concentrated" urine. The highest concentration will be in the morning urine, because. it has been accumulating for a long time - that is why pregnancy test should be done in the morning. And if you drink several glasses of water and do a test after that, the concentration of the hormone in the urine will be much lower.
• Take a look at the test. Often at very short terms you can see a very, very pale second stripe. If you notice such a "ghost" - it makes sense to repeat the test in a couple of days.
• Well, or just do not conjure with urine, but go to an independent laboratory and take a blood test for chorionic gonadotropin there. Of the minuses of the method, it is more expensive (the price of an analysis for hCG in Moscow is about 500-700 rubles, and the price of a pregnancy test is about 150).

Conclusion. On what day will a pregnancy test show a positive result?

Let's summarize all of the above.

How long before my period can I take a pregnancy test?

2-3 days before your period if you use a highly sensitive test and morning urine. However, the most reliable results are at the end of the first week of delay.

And some of the most common questions that a girl has in connection with pregnancy tests:

Already too long delay, and the test is still negative, how long to wait?

If the date of the last ovulation is known, and more than 21 days have passed since it, and the test is negative, then it is worth visiting a gynecologist to rule out the possibility of an ectopic pregnancy, especially if symptoms such as pain or spotting are present.

On what day will a pregnancy test show a positive result with an irregular cycle?

For an irregular cycle, count the most late date expected ovulation. Add the length of your longest cycle to your last period and subtract 14. This will be your ovulation date for that cycle. Add about 15-16 days to this date - at this time, the test should already show the correct result.

What does it mean if one line on a pregnancy test is bright and the other is pale?

Most likely you are pregnant. Repeat the test in 1-2 days, on the morning urine.

That's all. I hope we were able, if not to answer all your questions, then at least to give an idea of ​​​​what mechanisms mother’s body works on. early dates pregnancy. If you have any questions, you can ask them in the comments. And if you have already found two stripes on your test, then we advise you to read the article: “I am pregnant. 5 things to do in early pregnancy

It is no secret that many women at the planning stage want to find out as soon as possible whether conception has occurred in the current cycle. As soon as they start planning, expectant mothers stock up on tests in order to quickly see the cherished two stripes. But sometimes these stripes behave in a strange way: they seem to be there, but they seem to be not! So the woman first encounters the concept of "ghost" on the tests. Some pregnancy test companies are especially different, and give out a "ghost" in two out of three cases, regardless of the presence of a pregnancy!

One of our readers shared her experience of determining pregnancy using tests from two different manufacturers. The girl started the definition possible pregnancy even before the expected end of the cycle, and before the so-called "day X".

"Today I have the 26th day of the cycle. In the morning I did a test:

and it seems that he is quite "pregnant" ... Of course, I hoped that the second line would appear so early, but still I'm a little shocked.

The situation is this:

Today is supposedly 12 days post ovulation (DPO) with a cycle of 28 days, day X is still only 4 days later. That is, there is no delay.

I’m worried about the symptoms - somehow my stomach burns ... it doesn’t hurt, it doesn’t colitis, but I can feel this stomach, the uterus itself ((((Periodically. And it started after I showed my husband this test in the morning ... we have been planning for a year, Well, I wanted to please him ... maybe so early in vain.

Or maybe these burning sensations in the stomach on a nervous basis?

Has anyone had it so that the test before the delay is something like this striped, and then a breakdown? Did you have a burning sensation in the stomach in the early stages? Please, if you have something to say, don't be silent. And so hard. It's gotten to the point where I'm afraid to go to the toilet, I'm afraid to see blood.

P.S. I add tests on Day X and 2 days of delay. Sensations - nausea occasionally, the stomach is good, but sometimes I still feel these burning sensations.

The fear that everything seems to me that there is no pregnancy at all does not leave me. I'm afraid to relax and believe. Now I already think that I will continue to be afraid after the ultrasound, and after the beginning of the movements ... I need to read less sad stories, probably ..

two different tests (from two different manufacturers) on the 2nd day of delay:

dynamics Wonder tests: note that the Wonder test with a sensitivity of 10 at 2 days late compared to the Evie test shows significantly faint stripe. Maybe someone will need this information to be less nervous.

dynamics Evie tests:

Here is an analysis of the tests. Of course, I liked Eviks more, they are more reliable))))
