So I'm 16 weeks today with baby #2. All day yesterday and today, I've had constant cramping (I know some cramping is normal). This evening I started getting sharp burning pains across my stomach off and on. Sometimes it's worse than others and mostly when I'm not just laying around. Anyone else had this? If so, what was it from? Hubby wants me to go to the hospital to be checked but I dont want to go for no reason.
