A couple weeks ago I had sex with a man and I started to experience vaginal bleeding, even though nothing hurt too much. I figured we'd just gotten ahead of ourselves and we stopped. The next time I tried to have sex, with the same person it was extremely painful even after copious amounts of foreplay and we immeadiately stopped. There was a little blood but no where near the same amount as before and now I am still bleeding. It doesn't feel like a period and it's not the usual volume of a period. I am also on tri sprintec but recently have been intermittently taking it because I have a new job and I've been forgetting to take it
