So I was talking to someone awhile ago and we had unprotected sex.. I have felt weird ever since then. I did end up having my period it came early and at first I thought it was implantation bleeding but after five days it got really heavy and then after my period I had really bad cramps. I took many tests all negative. But my boobs have been sore ever since then and my next period should start soon but yet again I thought it was coming early because I spotted but have not bleed again since friday. I occasionally get weird pains right in the middle not ovary pain it doesn't last long but it hurts should I be worried I drink alot on the weekends, but I take a test first because I freak out thinking I could be poisoning my baby but they are negative I always think I am pregnant before and after every period and never have been in 10 years
