I've had 3
First one was at 40+12. I was given a 24 hour pessary which started my contractions and I didn't need to go on the drip or anything.
Second my waters were leaking at 40+5 so I had to be induced. This time I was given a shorter pessary (I think 2 or 4 hour) which started contractions. I was then put on the drip. She was born the next day.
This time around I was induced at 40+3.
They gave me a 24 hour pessary which started off contractions. My waters started leaking after around 18 hours with it in. So they removed it. I was left to contract naturally and then I was put on the drip a few hours later
Be prepared that being on the drip is a lot more painful than natural contractions. So be fully prepared to want/need an epidural.
I was fully against getting an epidural but once I was on the drip, that changed my mind quickly
Be prepared for it to take some time.
My 3rd was the longest.
The poor woman in my room had already had 2 lots of 24 hour pessaries, a 4 hour gel and she still hadn't dilated. They were about to give her a 24 hour break before starting again by the time I left.
However she was being induced early.
Usually tends to be the further over you are, the less time it takes
