Well lately I have picked up on working out again because I used to be a cheerleader, quit, got out of shape, still skinny, but I decided I wanted to start working out again, so lately I had been working out and me my boyfriend had sex about 3 weeks ago, I got my period about 2 weeks ago and my stomach looks bigger. Its only been about 3 weeks since we had sex. I think maybe im playing games with my head. Because I am having queeziness through the day, and I feel fatter. But I dont think its possible. Im gonna take a pregnancy test this weekend, im pretty sure im not. But I have decided that sex isnt for me yet and I have decided not to anymore, because its too much of a scare. Until I am ready. But could I be getting bigger in the ab region because im working out alot now? I dont know what to do
