Take a book and nice good. Might be a while.
I had 5 pessaries over 2.5 days and a 4 day induction but being overdue seems to make it quicker.
Once you have the pessary (inserted into cervix) they monitor you for 30mins and allow it to settle and check baby isn't distressed.
Then leave you 5/6 hours, come back and examine you then repeat. You can only have two in 24 hours so if unsuccessful you will be tested over night.
They will only break your waters (usually with a knitting needle) if you are dilated (mine was closed - not recommended). Then leave you 5 hours to wait for labour to kick in.
If it hasn't then they put you on the drip to ramp it up a notch.
You will be on the bed monitored, if baby is ok the keep going until 10cm.
The drip is notoriously painful so this is where people get pain relief. It's best to site the epidural usual before the drip so you aren't contacting while doing the needle.
Personally I wouldn't do it again, but I've heard second pregnancies and overdue are much quicker than early first births.
High risk of intervention and c section. I was refused a c section which I'm glad of.
