About an hour ago I started getting severe sharp pains in my right side starting in my back and going all the wat around to my crotch and half way down my thigh. I took a warm shower walked a little sat in different positions And laid down but nothing is easing it up!! My bladder is empty and I feel the need to pee and I'm starting to feel nauseous from the pain. I'm 39 and a half weeks please what is this!!!!!???
