I have been on my birth control for 4 months; and I take it every night at 10 pm sharp. Maybe I'm just being paranoid because I got my period last 27 days ago and I haven't gotten it yet. But I'm starting my third week of my BC today and it isn't due for another week but last month I got it earlier then usual.. Whenever my boyfriend and I have sex we do not use a condom but he pulls out right before he ejaculates.. Any help?? I'm so worried!!!
