Last week I was on the last week of blue pills(the dark ones) and I had unprotected sex(Friday.) I wasn't on any antibiotics, so shouldn't I have started my period already? I started taking the green pills on Sunday and still haven't started yet. Usually it takes a day to a day and a half for it to actually start. I feel like I'm about ready to but it still hasn't come, and I'm starting to freak out.
My boyfriend says he is 100% sure he didn't have an "accident" in or around my vaginal area, but I know he did on my stomach. He pulled out before he did, I know that's not a very good method, but I'm on birth control..shouldn't it work?
Could I be pregnant or am I just worrying too much? Can stress cause a late period?
Could someone PLEASE help?
