Am I pregnant?

I have never had unprotected sex before, but I was at my boyfriends house and we didn't have any condoms. One thing led to another. He was inside of me for a while longer than when we have condoms. And then when he was suppose suppose to pull out after he didnt. Instead he was just looking down at me smiling. Finally after a few seconds of me telling him to get off me, he rolls over. I head to the bathroom to clean up. He comes back and we do it once again in the bathroom counter. Anyway to make a long story short.

I had my period a few days afterwards. No cramps, it wasn't as heavy, and it was two weeks early. Usually before a peroid I know it's coming at least 3-5 days before. This one came too fast, too early, and no cramps. I'm waking up to pee in the middle of the night.....when usually I just pee first thing in the morning . It has now been two weeks. I'm slender built flat stomach and athetic. I'm tired a lot, but I do live in FL where it is humid all the time making everyone tired, hot, and annoyed. My boyfriend and I are no longer talking, so I'm in a complicated situation. This can all be in my head, but I can't help think about it. I just remember him being inside me too long and there was no ***. Either he didnt *** at all or he did inside me, but I didnt feel anything. HELP!!!! I always thought men *** throughtout intercourse pre-*** and regular ***?????
