i was the same way and after i had my baby they realized it was my gallbladder because pregnancy is number one cause of that
I've been having the same thing and get cramps evey night mostly on the right side. I been having morning sickness so bad I barely been able 2 eat anything without throwing up. Try eating sevral small meals instead of a few big ones. Or even just a few bites here and there is better then nothing.
If you can't eat maybe top up with fluids?x
Cramping is.normal I am pregnant with my 4th pregnancy I am 16 weeks and still cramp
