My boyfriend and I didnt necisarily have sex but he was wearing a condom and entered into me (i am/was i guess a virgin). we just wanted to try but it hurt to bad so we waited a minute and then he pulled out and then a bit later we tried again and the same thing happened. He was wearing a condom. Neither of us finished. I dont take any birh control. and this was on the 20th so its been 5 days and there are 2 days till me next expected period. I have been feeling very light headed (more than normal when I stand fast) so i was just wondering if everythhing is alright or if I am just being paranoid. ??? please tell me haha im trying not to freak out but kind of am
