Hello girls today im around 13 weeks. I went for an ultrasound tuesday and baby was perfectly fine and strong heartbeat! 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. I had cramping earlier in my pregnancy, but it was totally gone and now is back! anyone experienced cramps too?
