Im so curious about a spontaneous Water Break.

With my first, I was induced and having contractions for like 12 hours when my water finally broke at home and I went back to the hospital...

But for people who had spontaneous water breaking... whats it like? Like do you have any symptoms before hands? Braxton hicks? Cramps? Were you being active? It was it just like wake up and POP! Out comes a rush of water?
