When my water broke, I literally felt nothing until I looked down and saw gushes of fluid haha. Everyone is different! Ive felt a few pops in this pregnancy, but my midwife said it could be babys joint popping and such!
I never really felt anything but i woke up to a snap/pop and then felt a little of my water. I ran to the bathroom and by then it was all over the place. Trust me you'll know when it breaks.
