I really didn't mind having my waters broken, i certainly didn't find it painful at all. It did make the cx more intense but the process of having it done was no issue for me.
What did make labour more intense was the syntocin drip.

I am guessing because you are showing all the signs that your body is almost ready it wont take too much to convince your body to go into labour. You might find you only need a bit of gel or your waters broken and things will progress well.

I went into labour spontaneously the night before i was due to be induced with DD2. So you never know what the next 24 hours will bring. However it works out.......... how exciting! You're going to meet you new baby in the next 48 hours! Wooot! Good luck.
