I have been experiencing constant cramping in my lower abdomen all morning. I am 7w3d. I have had cramping on and off before which was normal but he fact that this is constant is what worries me. No spotting or severe pain though. I had a miscarriage last April and the pains were similar but from what I read those pains can also be very normal, so I don't know what to think. Anyone else having pains like this?
