I am on my 7th pack of birth control; and I take it every night around 10pm. One time i was three hours late but i didnt do anything that day.. 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 in the begining of my third week of my BC today and it isn't due for a couple days 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!!! You would think after so long it would come when its supposed to..
