Im roughly 5-7 weeks. I have not yet gone to the doctor as im waiting for my insurance to get approved. Well, me and my childs father had sex but about halfway through I started getting intense cramping pain just under my belly, about at my belt line. I let him finish but was in so much pain by the end of it I ended up crying. I have never experianced this pain before, and I am a first time mother. The pain lasted 5min and faded away, but it was so bad all I could do was curl up in a ball and cry. Any ideas on what happened? Should I worry?
