Light bleeding during sex~never happened before

My husband and I have been trying to get pregnant with our firt child for the last couple months, but he's in the military and has been away most of the time, but this month we actually were together while I was ovulating(11-13). I am supposed to start my period on this 28th (I have a 28 day cycle). So yesterday being 6 days after I ovulated I was cramping and during intercourse I had mild bleeding, but not since. I'm just wondering if anyone else has had this happen????

okay i have always been like clockwork... im currently 4 days late and we had sex today and after that i began bleeding very lightly not really crampy just the bleeding and i dont know whats going on... though i know that some woman do experiance bleeding in the first trimester. hope i helpsed ease your mind just a little
