I'm really stressing out. my stomach has been hurting very bad. I was supposed to get my period on the 9th. I haven't seen any like implantation bleeding and I haven't thrown up or anything. My boyfriend and I we're "Doing it" so he thought anyway. He was thrusting the outside of my vagina not in it at all at the top. he may have cummed. Is it possible that i could be pregnant?!? could it have run down or something? Supr worried.
