Hi there, my boyfriend and I have been having unprotected sex for months now. He pulls out almost every time. Lately, I have been getting feelings of nausea and not feeling to good. I can't lay on my stomach at all or for a long period of time because I get an un-easy feeling. I am feeling extremely bloated & am having alot of gas. I feel as if I have to poop and I go to the bathroom to go, and I'm mostly constipated. I am on birth control. But I accidently skipped a day. I feel as if I am about to get sick and nothing happens. Also, I get dizzy, am sleeping more & am getting headaches alot easier than I used to.. Help, could I be pregnant?!
