My best friend's cousin just got here not too long ago, we've known each other for the longest time though. We all grew up around each other. He told me how he felt. He said he was really into me and I was so happy because I was into him too. We hang out all the time with my best friend and her brother and others, he's usually there at all the parties too. We hung out alone a lot.. But one of their other cousins had a party and I was really drunk and so was he and we had sex... I hardly remember what we did exactly.. I just keep getting pictures in my head but I don't remember if he pulled out or not, he said he was careful but I'm really scared. I missed my period. I know because my sister starts a day or two after me and She's already done with it. My periods are rarely irregular and he has to go back for a bit and I'm super scared. I took a pregnancy test be we hunk it might be too early to tell. Any advice?
