Okay, so, me and my boyfriend haven't had sex yet, but something extremely close...not to get too graphic, but he was naked and so was I....we were fooling around a lot but no penetration occured. I'm now 3 days late on an always regular cycle. I'm on birth control, but while he was erect, he wasn't wearing a condom...I'm freaking out and I don't know if the chances of me being pregnant are even enough to think about it...help!
