ok...I am currently on b/c pills, and I have had regular light 4 day periods for the past year almost, beginning on Thursdays ending on Sunday nights. Perfect! This past cycle everything went on as usual. My boyfriend and I had intercourse on the Monday night(cycle had ended Sunday) and after it seems as though my period had resumed. By Tuesday morning it had stopped; Tuesday night, more intercourse, however everything was normal. And again on Wednesday night we had intercourse again, and bleeding resumed. This time I was still bleeding in the morning. I've been doing research all day, and I really can't figure out what's wrong. I know the answer I'm probably going to get is to go see a doctor. But I have no symptoms (I know for some infections, there are no symptoms) but we use completely protected sex by using condoms and regular use of the pill every time. Please...all I'm looking for is: "Its going to be alright" or "This has happened to me before" I'm freaking out...please help.
