Lolli, have your hospital given you a leaflet? My consultant gave me a general leaflet about induction. If they haven't, you could ask them for one.
Mine isn't specifically for diabetes, but it has good general info.
You could also Google for 'induction of labour' and the name of your hospital.
I'm going in in the morning if the day of induction, having 30 mins monitoring of me and baby, then having a Propess pessary which stays in for 24 hours. This is to soften the cervix. If that works and the cervix opens, they'll then try to break the waters. That may be enough or I may have to have a drip to stimulate contractions too.
I was worried about the pessary and wondered how quickly it works. I googled and found the average time it took to work was approx 19 hours. But for some women it worked quicker or slower. Some women can get crampy pains with it, while some feel nothing very much. The main thing to bear in mind is that it could be a long process so don't expect loads to happen very quickly. My leaflet said to bring books and magazines.
Once you're in established labour, you'll be moved down to the delivery suite. Often, they'll move you there too to break your waters, and they almost definitely will if you have the drip up as it can make strong contractions happen very quickly.
It's completely normal to worry - I am too! It's the not knowing how long it'll all take. I hope it goes quickly and easily for,you.
