With DD I had my waters broken and nothing else as far as interference. Sorry, I can't tell you how long the labour was after exactly, but it was still ages, and it was ages into the labour that my waters were broken. I think my labour was about 26 hours. How was it? Well, being my first, utter hell, so not sure I can answer that 'properly'.

DS was a short labour (7 odd hours), and he came all on his own.

Not sure I would recommend it (having your waters broken and "wait and see", but you do what you feel you need. I hope everything goes okay.
