Hi on the 27 March 2010, my boyfriend and i had sexual intercourse without a condom but he didn t ejeculate inside me, he withdrew before ejeculating (well hopefully) about 2 weeks after i felt little abdominal cramps,not painful at all, but took a home pregnancy test which came out negetive. well after about 3 weeks i got my periods, which were about 3 days late, they took longer than usual and experienced contraction like pain with things like blood clotts coming out, is it possible that i was pregnant?
