My boyfriend and I have frequent unprotected sex. Around the beginning of november, I got my normal period of about 2 - 3 days. After my period we had sex but there would be blood. We've tried for about a week, but I keep bleeding. One day we didnt have sex and I didnt bleed. Althkugh the next day my period came back. I had it for about 3 weeks after already having ut. Which it abnormal for me. Once my period was finally over , we started having sex again unprotected. After sex, it is normal for my stomach to hurt. Although last night after sex, I had a different kind of pain in my stomach. I felt sick, and I couldnt walk. I tried to stand up, but I would just get to the ground and curl up. The only way to slow down the pain was to put my knees to my chest and ball up. I tried eating maybe I was hungry , but food just made it even worse. It felt like u was going to get sick. Any idea on what could be wrong ? Im more scared about the abnormal pain.
