1. How long after you were induced did you actually give birth?
Well, if we're counting from the first application of the gel, then it was like two full days. If we're counting from when they started me on the drip and popped my water-bag, around four hours. Gel didn't even budge my cervix.

2. Once you had the gel on did you also have your waters broken or did they wait a bit?
See above. Had two applications of gel, not a millimetre of difference over 36 hours, so they just put me on a drip, broke my waters and in around 10 mins I went from 0 to 10cm and started pushing.

3. How bad is it really having waters broken?
Not bad at all. Not painful, if that's what you're worried about. I had my waters broken with both DD1 and DD2 (DD2 was a spontaneous labour but I was at 10cm for over an hour and no sign of any further progress because my waters were intact, so I asked the mw to break them to get things moving), and it was fine. DD1 there was a pop and a HUGE gush of fluid (all over the student midwife, oops), DD2 just a little gush and then things were moving spectacularly.

HTH Good luck with your induction!! The intense pains only come about if you're on the drip, and the synto induces your uterus to contract - if you manage to avoid it and just go with the gel, your body will do the rest naturally and it will only be as painful as a natural labour (which, from memory, is a lot easier and less intense). Try not to get too excited about the date, I was admitted and expected DD1's birth date to be 09/08/07 but nobody told me the gel might not work, so it ended up being nearly two days later
Wishing you all the best!
