Is a negative pregnancy test reliable 17 days after sex?

I also did tests in 13, 16, 17 days after intercourse and all negative

I also did a pregnancy test 13, 16, 17 days after intercourse and all of them came out negative, intercourse was the 8th day of the cycle, the last one it was, then nothing, neither for the fertile days nor afterwards, are the test results reliable?

Hello, I have a question, I take birth control pills, I was on an antibiotic and after the end of the antibiotic treatment 4 days after I had sex, my period was 03.03, the intercourse was 19.03, the test I did today 5.04 (negative)
And since 31.03 I had my period to see if the test is reliable

Hi everyone, I wanted to write for future worried girls how it went on for me. Tests where I saw the shadow of the second line turned out to be steam lines. My menstruation was delayed for 16 days due to stress. On the 51st day of the cycle, bleeding finally appeared :)

That's what it looks like, on pink I think you can see it. Thank you for your earlier reply. Plans to repeat the test tomorrow (17 days after sex)

To @Kassi:

Hello, in this case, the result of the pregnancy test is inconclusive. Tests read after the time indicated in the manual (usually 5-10 minutes) may give false positive results due to the so-called "evaporation line".

For a more reliable result, I encourage you to repeat the pregnancy test in 1-2 days, preferably in the morning with the first urine that is most concentrated. A blood test for the presence of the hormone beta-hCG can also be performed – this is the most reliable method of confirming pregnancy at an early stage. If menstruation still does not occur, it is worth consulting a gynecologist.

Hello, 14 days after intercourse I did a test in the morning, first it came out negative. After a few hours you can see a shadow of the second line, so inconspicuous that you can't see them in the photo and 2 people said that they don't see them either when looking live. Should we still take this test as negative or already positive?
The next day at 1 p.m. I did the test again and it came out exactly the same, first negative, then a hardly visible line. I haven't drunk anything since I woke up. At that time, it was the 3rd and 4th day of the expected menstruation

Hello and what I found . I'm in a similar situation. I still have no menstruation ://
