I've missed a few periods before, but normally just a month. I'm 17 years old, and my last period was in early November. After my period, my boyfriend and I were doing stuff - not really sex! but he kind of pushed up and went in a bit. I've taken a test, which came back negative pretty much a month and a half after that. I haven't had any signs of pregnancy at all. I am overweight for my height, and I don't know if that could be playing a role in it. I don't think I am pregnant, but I am kind of scared that it could be a possibility... What should I do? I haven't felt anything different tha normal, my boobs aren't sore, and I'm eating normally. I have been urinating more than I used to, but I walk a lot more now then at my other school. I figured I'd ask to see other peoples opinions...
