Weird stomach pain..

If you can, take your blood pressure and watch for other symptoms of pre-eclampsia, spotty vision, headaches, etc. If blood pressure is high, call it in! Otherwise I wouldn’t worry too much, gas pains, odd Braxton Hicks, muscle stretching, etc.

could be gall bladder

I would tell your doctor. I had weird stomach pain that turned into my belly being constantly hard. I thought it was Braxton-Hicks but it got to be really uncomfortable. I ended up going to labor and delivery and found out it was a UTI. Always best to call!
