I had sex n got my period in may. how can i tell if it was period/ implantation bleeding? i had it for 6 days. didnt get my period in june which i was suppose to get on the 24 rightfully. did a few pregnancy test all came back negative?

A positive pregnancy test can tell a woman that PRIOR spotting was actually implantation spotting. It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a very reliable result about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period.
