Should I go get checked?

I’m having Braxton Hicks and I just started getting very mild cramping down below. Idk if it’s dehydration as I’m on my 4th bottle of water right now but I think I maybe ate to much today and now my stomach just feels tight. But it’s also getting hard as well.. I’ve been to the hospital for BH before and they told me drink more water.. I don’t want to go again because I’ve been plenty of times already as a ftm.. but idk if i need more water or what. The mild cramping is the part that’s getting to me. 30 weeks tomorrow
