HI, i have been experiencing pain under my left rib, it only hurts when i make certain movements, cough, laugh, sneeze, or anything that involves flexing mu upper left quad. it feels like something is popping out of me. I went to my doctor 3 days ago, he said to wait 1 week and if i', still in pain to come back and he'll schedule me for an ultrasound. I had already waited a week before seeing him, and them pain just gets worse everyday. I found out yesterday after missing my period that i am pregnant. Do you have any idea what could be causing the pain, also is it something i should go to the hospital to get checked?
