Oh how exciting, your baby will be here soon!!
I was induced with both of my boys at 36 weeks and 37 weeks.
First induction - pessary started working at 27 hours, felt like period pain, and was checked and I was 1cm and moved to delivery suite. I had epidural straight away and then they broke my waters shortly after. Induced 6pm Friday, baby born 3pm Sunday, after arriving in the labour suite in the middle of the night. All straightforward!
Second induction- first pessary didn't work after 30 hours, second pessary worked after ten mins- killer contractions with no gaps, so they took it out again very quickly. I had then gone from no cm to 3cm, and taken to delivery suite to have waters broken. Again,had epidural and normal birth.
Both labours I went from 4cm to 10cm dilated within two hours, so once it got going, it got going quickly! Epidural helped with the pain, only right towards the end of contractions was I feeling it.
Good luck- you'll be in safe hands and baby will be here soon
