"PERIOD CRAMPS"'at 33 weeks pregnant?!?!

Jan

I'll be 33 weeks pregnant on Sunday. I'm feeling an different feeling (not painful or uncomfortable) in my tummy and period like cramps in my uterus. I had the same

Feeling at 37.5 weeks with my first son, and my water broke that night. Should I be worried if that did happen?! It's super early!! I'm going to see my doctor on Monday but has anyone else experienced this feeling at 33 weeks or a similar time frame?
