12 13 dpo test negative. Why is it better not to take the test before the delay?

Thirteen days after ovulation (13 DPO) and the test is negative? You shouldn’t unequivocally assume that “it didn’t work out again” and get upset in advance. At such a short period of time, not all tests to determine the concentration of the hCG hormone in the urine will show exact result.

From what day do you count your period as late?

Many errors early diagnosis Pregnancies happen only because women do not know how to calculate their menstrual cycle. You definitely need to have a special calendar. It regularly marks the days when menstruation begins and ends. Several months of working with a regular paper calendar or a special smartphone application will allow you to thoroughly study the features of your menstrual cycle. This is important for determining the moment of ovulation and delay.

Duration normal cycle averages 28-30 days. Frequency is an individual indicator. Therefore, for every woman, menstruation can be either short (3 days) or long (7 days).

Your period may start a little earlier or later, and this is not a cause for concern. The moment of the onset of menstruation directly depends on external and internal factors: hormonal disbalance, stress, climate change or time zones, poor nutrition, women's diseases and, of course, pregnancy.

To understand whether this is a delay, or the cycle has been slightly rearranged, you need to look at the calendar. It marks the end date of the last menstruation. From this day you need to count the usual duration of the cycle. For women with irregular menstruation another option has been developed. Here the longest and shortest cycles are added together, and then the resulting figure is divided by two. For accuracy, you can calculate the arithmetic average of the last three to six menstrual cycles. By the way, all this is done independently by the mobile application.

The day of ovulation is determined in the same way. However, when irregular cycle figure it out this issue it will be more difficult. If the number of days between menstruation is approximately the same, then it is enough to subtract 12-14 days from this figure. This will be the approximate day of ovulation. Sometimes the release of an egg from the follicle can occur closer to the end of the last menstruation or the beginning of the next. With an irregular cycle, ovulation can only be determined using special tests.

Why shouldn't you trust the results before the delay?

When will the test show pregnancy, if any? Most special strips can be used from the first day of the delay. However, you should be aware that there may be negative test and at 13 DPO. This is not surprising, since in a cycle lasting 28 days, it falls just on the last one. That is, in fact there is no delay yet. The concentration of hCG may not have yet reached the required minimum for the test to “react” to it.

The strips have a sensitivity of 20-25 mIU/ml. Recognize before delay interesting situation Only expensive and high-quality pregnancy tests can. Within seven to ten days after the expected conception, strips with a sensitivity of 10 mIU/ml can determine whether a woman will become a mother in the next nine months.

Will the test show pregnancy on the 13th day after ovulation (DPO)? After all, almost two weeks have passed, and it seems that this time is enough to determine an interesting situation. In fact, this is a very short period of time. When there is no delay in menstruation yet (including at 13 DPO), a negative test should not be taken seriously. For getting reliable result It's better to wait a few more days.

Pregnancy tests for use at home respond to the hCG hormone, which begins to be produced only after the embryo has implanted. Implantation in 18% of cases occurs at 8 DPO, in 36% at the ninth, and in 27% at the tenth. On the remaining days from 3 to 12 after ovulation, the probability of implantation is less than 10%. After attaching ovum should begin to produce hCG - a specific pregnancy hormone ( human chorionic gonadotropin). For the test to accurately determine pregnancy, the hCG level must reach at least 20 mIU/ml.

"Ghost" stripe

A negative test at 13 DPO can also occur during pregnancy. It’s just that the level of the hCG hormone is not yet sufficient for the reagent to react and clearly show the second strip. But at the same time, some women see a pale line on tests. This result also cannot be considered reliable. The test needs to be repeated in a couple of days.

The line of evaporation is also called a “ghost” stripe, when there was a colored mark, but after a while it became completely invisible. The Phantom has the same width and length as the control sample. It is colored blue, pink or lilac, but is paler and barely noticeable. In some ways, the “ghost” resembles a smoky trail where there should be a brightly colored second stripe.

Negative test at 13 DPO: is there hope?

Since there is no delay on this day yet, this result does not mean that there is no pregnancy. Of course, it's hard not to worry when there have already been several unsuccessful attempts conceive a child. However, you will have to wait. To worry less, it is recommended to distract yourself. The results of numerous studies prove that a woman who experiences stress has a better chance of successful conception decrease by 12%.

In the first two weeks after implantation, the hCG level doubles every 1-2 days. If the fertilized egg entered the uterine cavity on the fourth day after ovulation, then at 13 DPO the hCG level will be only 2 mIU/l. At 5 DPO this figure will increase to 4, at the sixth - to 8, at the seventh - to 16, and at the eighth - to 32. Ultra sensitive test will show pregnancy a week after ovulation. Normal - on the eighth day. But this is only if the woman knows exactly the day of ovulation, having determined it not by a schedule or tests, but by ultrasound. After all, the probability of attachment at the third to fifth DPO is only 0.68%. And the fertilized egg can produce hCG at different rates.

If we take average statistics, everything will go even slower. For example, implantation occurred on the eighth day after conception, and hCG increases by 2 times every two days. Therefore, at 9 DPO the hormone concentration will be only 2 mIU/ml, at 11 DPO - 4, at 13 DPO - 8, and at 15 DPO - 16. On the first day of the delay, even a high-quality sensitive test will show only a weak second line. But on the third day you will be able to admire the bright and clear line.

It happens that pregnancy develops even more slowly. It's quite normal. Conception at 10 DPO occurs in 27% of cases. Then the hCG will “grow” to 16 mIU/ml only on the third day of the delay, or at 17 DPO.

How else can you find out if pregnancy has occurred?

When will the test show pregnancy? It is possible to reliably find out whether the delay was caused by an interesting situation only on the third to fifth day of the delay. By this point, the hCG level will reach the required minimum, even if implantation occurs late and the embryo is in no hurry to synthesize the hormone. If you can’t wait to find out if you are pregnant, you can do a blood test to detect hCG at the clinic. Blood is donated from a vein in the morning on an empty stomach. The laboratory will also determine the exact gestational age.

Medication support

For some illnesses or unsuccessful attempts to get pregnant, the doctor may prescribe an appointment medicine. For example, Duphaston. And at 13 DPO the test was negative. Should we cancel Duphaston in this case or not? Before making a decision, the doctor will send you to a laboratory for a blood test. Further actions will depend on its outcome. If pregnancy is confirmed, then Duphaston is usually not canceled for some time. If conception does not take place in this cycle, then the medication should be abandoned.

Thirteen days after ovulation (13 DPO) and the test is negative? You shouldn’t unequivocally assume that “it didn’t work out again” and get upset in advance. At such a short period of time, not all tests for determining the concentration of the hCG hormone in the urine will show an accurate result.

Why you shouldn't take the test before the delay? yes, at least from savings, and if you don’t have a lot of money, from common sense. Let me explain why. The test reacts to the beta subunit of hCG (human chorionic gonadotropin), which begins to be produced only after implantation of such a tiny fetus of your love into the endometrium, and this happens 3-12 days after conception. Of course, if this fruit is a sprinter, then the chance of seeing the coveted second stripe is greater than ever. But I’ll immediately cool your possible ardor: the value of this chance is 0.68%.

3-5 dpo - 0.68%

6 dpo - 1.39%

7 dpo - 5.56%

8 dpo - 18.06%

9 dpo - 36.81%

10 dpo - 27.78%

11 dpo - 6.94%

12 dpo - 2.78%

What if the fruit of love is unhurried? Why get upset ahead of time? After all, it’s enough to wait just a few days to know for sure. ABOUT! I can directly see the indignant faces of those especially suffering (I myself was in their place!), because in these few days you can die of impatience! they will say so and they will be right, of course, but for me it is much worse to die from disappointment. Yes and good tests- pleasure is not cheap. It’s better to buy yourself an extra kilogram of apples, really!

It’s not for nothing that I mentioned GOOD tests. Let's talk about this in more detail. The famous “ghosts” that those suffering are so happy to believe.... Oh, these ghosts that make you sob into your pillow! In bad, cheap tests, the reagent can also be bad. And he reacts to everything...

By the way, the same good tests can falsely show a second line, and in vain many people sin on tests, it is their own “fault”. Wikipedia kindly shared the following information with me: human chorionic gonadotropin has the biological properties of both LH and FSH, and binds to both types of gonadotropin receptors, but the luteinizing activity of hCG significantly prevails over the follicle-stimulating one. HCG is significantly superior in luteinizing activity to “regular” LH, produced by the anterior lobe of the pituitary gland.

Next we turn on the logic. What if LH is, so to speak, not ordinary? Well, that is, its level is off scale beyond normal for the second phase of LH or is it some kind of cyst? or some other bug? this is Y healthy woman the test just won’t show a “ghost”! But how many of those who wait for years for a stork are truly healthy? hmmm.... here come the tears into the pillow. But the fact is that the test reagent reacts (forgive the tautology) to abnormal LH and, instead of pregnancy, shows hope for it, which is immediately and mercilessly taken away by the coming menstruation. And the awaiting aista thinks "Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaao! Away I’ve dreamed about fish twice already!” It's not that I don't believe in omens or that I deny unconventional methods. No! what do you! I screamed like that myself. I just want to give food for thought. And finally: early miscarriages do happen. Yes, they do exist. But what's the point in shedding tears? It’s much easier to go to the laboratory and find out your hormone levels so that you can bury yourself in your pillow and sleep peacefully, and not sob into it, exclaiming “Why do I need this, Lord! I want it that way, but the alcoholic Alla, s...a, already gives birth to a third healthy one after six abortions, ahhh!”

Okay, let's move on. There are no problems with hormones, we have already found that out. But there is impatience. Moreover, there are some insidious tests, expensive and good, which promise to show the result, if any, even 4 days before the delay. Is it necessary?

Do we remember about hCG during implantation? Let's take a sprinter for example. Well, yes, the same sprinter who, already at 3 DPO, screwed himself into mommy as hard as he could and let’s produce hCG. So, for the first 2-3 weeks, the hCG value in the blood doubles every 24-48 hours. Well, if our baby is a sprinter, let’s take it as a truth that his hCG doubles every 24 hours. Wow!

At 4 DPO the hCG value is 2, at 5 DPO - 4, at 6 DPO - 8, at 7 DPO - 16, at 8 DPO - 32 - oops! at 8 DPO, a test with a sensitivity of 25 will show clear two stripes. But this is only if a woman clearly knows the day of ovulation (not according to a schedule, but from an ultrasound!), her baby is a sprinter - 0.68% probability, and even produces hCG at breakneck speed. The probability of such a scenario is less than 1%.

Now let's look at the average scenario. Implantation at 8 DPO and hCG doubles every 48 hours. At 9 DPO - 2, at 11 DPO - 4, at 13 DPO - 8, at 15 DPO - 16, i.e. on the first day of the delay, the test will show a weak line! and on the third it is already clear and bright.

Well, what if the baby is delayed in attaching? At 10 DPO, as many as 27% of cases occur. Let's count!

11 DPO - 2, 13 DPO - 4, 15 DPO (first day of delay) - 8 in total, 17 DPO (3rd day of delay) - 16, i.e. a faint strip can be seen only on the 2-3rd day of the delay, but not before it. And is it worth crying?

Would you say it’s hard not to cry, not to worry, not to count? Yes, it is difficult. I know. She cried, worried and counted. Yes, just to pull yourself together and distract yourself (it helped me), it’s enough to know the following: “British scientists conducted research on the effect of stress on women’s ability to conceive. Studies have shown that in women experiencing the greatest stress, the ability to conceive decreases by 12%. The study involved 274 women aged 18 to 40. Moreover, the fact is that after several unsuccessful attempts to get pregnant, a woman begins to experience even more stress and the chances of conceiving fall even further."

Why reduce your chances of becoming a mother with tears and hassle? here is the answer to the question, why do alcoholics give birth easily, while we, who want and wait so much, cry into our pillows? because alcoholics don’t worry, they don’t have stress. Therefore, it is necessary, if not to completely “de-cycle”, then at least not to do tests before the delay. Since disappointment is very likely, which is oh so undesirable for those planning a pregnancy!

I'm not talking about those who are in the IVF protocol, who have been diagnosed serious problems, requiring the most early definition pregnancy. But as a rule, in these cases, the woman is under the supervision of a doctor and donates blood to determine hCG, and does not look out for ghosts in the tests.

It was a long article. Thanks to those who read to the end! maybe it will help someone. I do not care at least, this knowledge helped a lot. And I’m also a plush person, I like to save money. A pregnancy test costs at least 50 rubles. If you don’t do tests after 10 DPO, in total it’s at least 5-6 tests = 250-300 rubles; with a year of planning experience, you can save 3000-3600 rubles and a lot of nerves in addition. For 3,000 rubles you can buy your baby new onesies!

And pregnancy comes when you least expect it. This is no longer from the Internet, but word of mouth has worked. Of all my acquaintances who were concerned about the problem (I’m not talking about those who simply said “let’s try” and gave up, moving on with their lives and rejoicing), only one couple managed to get pregnant as planned the first time, and then only under the IVF protocol. The rest went through all the circles of hell until they learned to live without thoughts of pregnancy. And then it worked!

I'm 10DPO today! Well, no signs at all, it seems to me, except for some imaginary ones or something. Like nausea and something like that)

Last night, at 9DPO, I took a test, well, I’m a dough addict, yes) And it gave me a weak second line) I ran to my husband with shaking hands) And he sees it! Ahh! I barely survived until the morning!

I did it this morning and I’m just as pale! And now I took the test again, I’m still afraid that the strip has disappeared) And then I see that it has brightened)

The top test was last night at 9DPO, at 9 o’clock, the bottom one just now, at 10DPO)

I track ovulation using tests, so I can probably say for sure that it happened last Monday)

4 days until your period! They shouldn’t come on Monday anymore!)

Girls, when did your test show pregnancy???

Oh. He lied about the clearable, he showed it to me in 2-3 weeks. And then again on the 23rd day it showed 2-3 weeks. I was very scared. Lied like a turd.

Hi all! I just found out today, 13 DPO 2 strips, Mom Test. What to do next?

VikaFawal, I haven’t had my period yet, but the test showed 2 lines...

My first weak line was drawn at 11 dpo, and at 12 dpo it was already clear

Hello! I have eco. Ghost - at 5 dpo with five days (like 10 dpo), the next day it is already brighter and brighter

Girls, I still have 5 days left before my delay, but my test shows 2 stripes, one is bright and the other is not... is this possible? and is everything okay? Is there a pregnancy or something wrong?

At about 12 DPO, I did it in the afternoon, the stripe was pale, two days later both stripes were already equal in brightness.

The very first ghost appeared at 14 dpo, but quickly darkened - a day later there were 2 clearly visible

The first day of the delay there was a faint ghost of a stripe, and on the 7th day after the delay there was already a bright second stripe.

I did the test on the 7th day of the delay, it immediately showed a second obvious stripe, not the same in brightness as the control, but bright)))

Girls, at 11 DPO I took a test at about 6 am. Negative. There wasn’t even a ghost... at lunch I did a jet (also Evi) - a second stripe immediately appeared. Quite clear, although somewhat pale. But she was clearly visible. At 12, 13 DPO the tests are negative.. there is not even a ghost.. how can this be explained, can anyone tell me?

Is there nothing else to do? if there is B, there is no escape from you, is it really impossible to wait for the delay and do a test, and then go for hCG? Well, what's in the tea leaves - guess what? New21 July 2013, 12:37

You know, sometimes people take pills, and it is very important to know in advance, otherwise there may not be a delay. The sharpness is always amazing, you might think someone is forcing you to count the days until the delay New July 21, 2013, 12:42

Then they go to the doctor and solve this issue, go to take hCG on the appointed day. Well, what can we see from the photo? I always have this test before my period. But I'm not pregnant. New21 July 2013, 12:45

So the doctor says to do tests until there is no ghost, and immediately for hCG. There has never been a false positive, which, by the way, is not good

• “I would be glad... it’s just that last month the tests were also striped, but my period started 2 days earlier ((there was a miscarriage along the way, they were still striped after M... and then they stopped, and now they’re starting to show // again...
• 09/14/12 21:38 “yeah, perhaps when there is a pregnancy, this hCG appears immediately, and not after a delay, it’s just that then its concentration is already high! Congratulations to you!
• 09.14.12 20:01" Why not =) my test sparkled at 9 DPO.. and the stripe is not pale, but it’s clear, but the ultrasound showed it 3 days before the CD =) Now the stripe is cooing next to me hehe =)

Well, it happens that you can see it this way, but not in the photo. Do it at 12dpo next... I already had bright ones at 6-8-10dpo, you can look in my gallery, even in the photo everything is clearly visible.. What is your test sensitivity? Mine simply allowed them to be done from 5 dpo already.. April 3, 2013 - 08:12

Well, it happens that you can see it this way, but not in the photo. Do the next one at 12dpo... I already had bright ones at 6-8-10dpo, you can look in my gallery, even in the photo everything is clearly visible.. And what is the sensitivity of the test? ?Mine simply allowed them to be done from 5 dpo already .. This is an Evitest, sensitivity 20, during my first pregnancy the test did not show for a long time, only on the first day of the delay there was a barely visible line, I even threw it away at first)) April 3, 2013 — 08:35 Sorry, but I don’t see the second line either, and a test with a sensitivity of 20 is unlikely to show it that early. Buy it at least with a sensitivity of 10 and do it in two days. Although I understand you perfectly well, I want to find out everything quickly, I recently went through this myself. I peered nervously at the tests. By the way, you can take a blood test for hCG, it will definitely show whether you are pregnant or not. That's exactly what I ended up doing. April 3, 2013 — 08:45

Thank you, don’t apologize) I really don’t have enough patience, it’s just that our first child turned out right away, so with this I want it to work out right away, so that the kids don’t have big difference aged.
