Hello girls Im 13 weeks. I went for an ultrasound tuesday and baby was perfectly fine and strong heartbeat! (you can see the ultrasound pic in my profile) This past couple of days Ive been cramping when I want to pee. im guessing for the pressure in my bladder. Today Ive had this on and off cramping, it feels inside but low. I read cramping is normal but i worry. Its like a pressure, it comes and goes but it can get very sharp at times. there is NO bledding whatsoever. Im guessing it could be streching, but i worry. Im calling my doctor tomorrow to make sure everything is ok! I would like your guys imput! Its like period cramps but different, very hard to explain! I can also feel it at times in my back I had cramping earlier in my pregnancy, but it was totally gone and now is back! anyone cramping or cramped?
