With my daughter my water broke at 37 weeks at 1:30 in the afternoon and she was delivered at 1:30 in the morning, I had zero warning or clues or anything that I was going to have her that day. This time I have no idea what to expect! I'm having BH this time and my back, pelvis, crotch.. It all hurts and I was never sore like this with my daughter.. So tell me your story! How did you know it was "time"?
