Can a pregnancy test performed on the 20th day after intercourse be considered correct?

To @Majaaa:

Yes, you can rule out pregnancy.

Good morning. I took a beta blood test, 12 days after intercourse it came out 0.2 mlu, 18 days later I took a pharmacy pregnancy test, it came out negative and on the 20th day to be sure, I took the pharmacy test again, it came out negative, can I be sure of the result?

To @Czarna: Negative test results mean no pregnancy. More here: https://www.gdziepolek.pl/artykuly/test-ciazowy-jaki-wybrac-i-kiedy-zrobic

Hi I have the same question .. The test is done 10, 14 and 20 days after intercourse. All negative. There is not even a trace of the second line. Should I already consider myself reliable? My fears started with the fact that this month my menstrual bleeding was different than ever. It started with spotting for one day, then there was a stronger bleeding with clots for 2 days. After the period, pain in the lower abdomen and ovaries began. And so for a few days. I already have an appointment with a gynecologist on Wednesday
