Hi, so Ive been having these pains in my lower stomach, when I try to sit or bend over, and now today it even hurts when I try to walk. They started after I started having problems with my menstrial cycle. I had an ultrasound done last year due to the fact that I was late by 3 months, and constanly throwing up. I never had sex so I cant be pregant. But the stomach pain comes and go as it please, but lately its been worse. The doctor said my ovaries looked fine, so I dont know what else it might be.
