So me and my man last had sex 16 days ago I’ve took multiple pregnancy test within them days and I’ve gotten a few positives and three negatives more positive than negative well today I started bleeding very light so far mind you is been 16 days since! And my period is not supposed to come until the 25th . I also took an ovulation test on the 13th which was very faint and then I took one yesterday the 18th and it was a very bright line I was told that ovulation test can pick up early pregnancy but I’m not sure . Could this possibly be implantation bleeding or not
