heavy lifting like an idiot

So I'm an idiot. I just moved a bed... I mostly slid it but there was one part where I had to pick it up to get it around a corner. We are talking a queen size bed here. And I'm 22 weeks pregnant.
Well now my stomach is a bit crampy. I had some bathroom issues this morning, so it could be gas, but I still can't help but worry. Just wondered if anyone had any advice to ease my mind!
