I wasn't cramping either but like @theirmommy1416 said you can catch an infection so I wouldn't risk it personally. When I told my Dr that O was leaking all he said was go to the hospital!! I was like, really??? lol I didn't realize that the baby could be in danger. But that's my opinion. I would just call anyway if you don't want to go to the hospital.
I'd go to the hospital to get checked rather wait and risk infection . cause with my second son my water broke but didn't have contractions till I was at the hospital.
