I'm Brittney I'm 21 years old and I'm a sexual active person. Every now and than I masturbate when I get in the mood. Lately since I've had my first child when I'm about to orgasm or get off whichever, I have a sharp cramping pain I'm my abdomen lower stomach area around the belly button, sometimes it's only on one side and others it's all across. What I'm trying to find out is if it's normal or not and do I need to go see a doctor about it?
