I'm 22 and my long term boyfriend and I live 3 hours apart while I'm at college. Three weeks ago I went to visit him over the weekend. The week before that I had run out of birth control pills and tried to get more, but couldn't get scheduled until the weekend after I visited my boyfriend.

So the week before I visited him I had my period. When we were together we had unprotected sex (no condom for him, I hadn't had a pill in about week) and he pulled out before he ejaculated. This was 1-3 days after my period ended. I can't remember exactly.

The weekend after I got back I got more pills and have been taking them regulary and on time for two weeks now. Yesterday I started getting dark red almost brown spotting and its just gotten worse today.

I'm very worried that I might be pregnant...
