Okay I can't take birth control I am allergic to it, but my boyfriend and I use condoms. Well one night he finished, and when he finishes he pulls out just in-case, so when he went to put another condom on he wiped himself off with a piece of clothe, but he got some on his hand and he wiped it on the sheets then he put on the condom. Now i haven't had my period, but I was supposed to start my period the next day, but I didn't and I am freaking out!!!!!!!!!!!!!!!!!!!!!!!!!!!! SOMEONE PLEASE HELP!!!!!!
