So, me and my ex boyfriend (not by choice... Parents made us break up) had sex tonight and I'm not on birth control or anything... But he was wearing a condom then took it off (said he don't like it like that) and then a couple minutes later he pulls out and cums all over my belly... &&asked if he got it in me.. But I didn't feel anything. I had my period this month (way before tonight) then next month is going to be around the 15th because I usually start around there.. Should I be worried? Do I take plan b?
