I was terrified about my induction, but it really was fine.
Mine was my second birth, after all-natural blah blah blah first birth.
Waters went at 38 weeks and baby found to be very small, so went straight onto drip, no pessaries.
I was still able to be fairly upright and active, despite continuous monitoring. The monitoring was quite fun tbh, seeing the strength of your contractions on the graph thingy.
I made very little progress from 10am to 7pm (3 cm) and they gave me 3 more hours til a C section, when I had diamorphine. (I'd just had gas and air and TENs up til then.)
Within half an hour of getting the diamorphine, I was pushing. Pushing stage lasted about 10 minutes (second baby though). The midwife said it sometimes happens like that, the morphine makes your body relax and just dilate. (Sometimes it can go the other way though and slow you down.)
If you are wired up and can't have a water birth, definitely get a TENs. I know they have mixed reviews but I found mine really worked as a sort of counter-sensation / distraction.
But mostly, go with the flow, try not to worry. As MrsCakes says, write alternatives for your plan rather than absolutes.
Good luck, I hope it goes well.
