I'm about 5 weeks pregnant and two days ago I had extremely painful and sharp pain in my lower stomach. Everything I read asks if the pain is on the left side, the right side, or both, but my pain was in the MIDDLE of my lower stomach. It hurt so bad I was crying hysterically and I took some tylenol. The pain lasted about 5 minutes and it was constant, it didn't come and go. Also, it was right after intercourse so I don't know if that has anything to do with it. Since the pain, I have been checking for bleeding and there has been none, so I'm really hoping that is a good sign. And the pain hasnt come back, although I havent had sex since. I'm not scheduled for an ultrasound until 8 weeks. Please help, I'm so scared of having a miscarriage. This is my first pregnancy.
