Hello, on the 14th day of the cycle, the day before the planned ovulation, I had intercourse during which the condom slipped off to the middle of the penis, the partner did not, but there was pre-ejaculate in it, we were not sure if nothing came out, so I took escapelle, 9 hours after intercourse, I did tests super sensitive, 10mlU, 10.12 days after intercourse, and on the 15th day, a test with a sensitivity of 25mlU from morning urine, all negative, on the 30th day of the cycle (the day when the period was supposed to start)I started to have brown light pink spotting visible only on paper, after urinating the next day I had normal bleeding with visible small blood clots, and today again only a slight brown spotting and only in the morning, so please answer, could it have been implantation bleeding? Could the tests have been done too early? Is it just a scarce period, I will add that tomorrow I am going to do a super sensitive test, or will it be reliable?
