Thursday I had unprotected sex and the guy came inside me when we were doing the "riding position". Friday I felt fine and yesterday out of no where, I felt so nauseous as if I had food poisoning. I took some Pepto Bismol twice and I've been sleeping all day as well. But, I'm dizzy also. I did try to use the bathroom to take a BM 💩 and somehow I can barely use it. I know it's too early to tell... My period came on September 10th and it usually comes on in the middle of the month or end. I know I've been ovulating this week which I know for a fact started on the 17th-22nd. Could I be pregnant?
