Painful gas, and Braxton hicks

Whenever I eat I get painful gas, and the urge to go to the washroom. I'm 26+ weeks and experiencing Braxton Hicks I think, my uterus contracts and I feel like peeing all the time. it's my first child and these contractions freak me out. This only started today.

Is this normal? I'm trying to drink more and more water and I'm practically just in the washroom.

Anything that would help with the gas and funny stomach
