Ok...I have a question. I had my period over this past weekend (10/28-10/31) I was supposed to start a new pack of birth control on sunday (10/31) I forgot to pick up my prescription until tuesday (11/2) so I was like 3 days late starting it. My boyfriend and I had sex on 10/31, and 11/2 . Now yesterday my boobs were hurting really bad. It doesn't hurt if I touch them, it hurts to wear a bra, it hurts to not wear a bra, it hurts to lay on them...Etc. They are still hurting today, and I work up with a really really bad back ache. I can't even sit without it hurting. There wouldn't be any chance that I could be pregnant is there? If I was, the symptoms wouldn't be here already would they? Please help!
