I'm needing some help trying to figure this out. Last week I had sex with my boyfriend and after a couple hours I started getting sharp pain in my lower abdominal. I slept it off and it felt it went away. But the past couple of days it came back, stronger and more sharp as if every move I made made a pinch to my abdominal. Sex has become painful to where he can't get in all the way and I've been wearing a heating pad. I'm not sure if this is an early symptom of pregnancy or what, but its pretty painful as if things are being pushed down in my abdominal following with SHARP pains.
