Constant stomach distress while pregnant?

I’m pregnant with my second. With my first I had cholecystitis my whole pregnancy and got induced to get my gallbladder out because I had lost 30+ lbs and I couldn’t even drink water without pain.

This time, I have CONSTANT diarrhea with stomach cramps. Not uterine cramps, but actual intestinal cramps. Just checked on baby and they’re healthy with a heart beat, so I’m just so confused as to why I have violent diarrhea all the time.

8 weeks pregnant now
