If I can remember correctly (it's been a whole 5 years now ) when my 1st DD was born, my water broke at home, but I was not contracting at all. Also I was barely a centimeter dialated so they said it was too early for pitocin. But they inserted something on my cervix to help it dialate.I had to stay in the hospital, because my water had broken. It took about 6 or 8 hours but it did start to work and then when I was dialated enough (yet still not contracting), they started pitocin. After that it was about a hour and I was ready to push. I had the baby vaginally, she was 7 lbs, 2 oz.
