Has anyone suffer a really bad stomach pain while pregnant?

I had a glass of water and drank it so fast because I felt thirsty. For 5 seconds I wasn’t breathing much because I was chugging it. I had another cup of cold water but took two sips. For some reason the top of my stomach hurt so bad. It almost felt like trapped gas I think. I don’t feel like I have to let any gas out but the top of my stomach hurt once I laid down on the bed. To fol it off I ate a lot a couple of hours ago and my stomach feels so hard. It feels like its going to pop God forbid and i’am only 26 weeks pregnant
