I had an induction a week and a half ago. My waters had already broken but I was not having very regular contractions and they were quite weak, so they induced me due to risk of infection.
I had the postglandin gel at lunchtime on Thursday. I was put in a very nice private room with things like a birth ball and I set up a speaker with my music. The plan was to stay there until I was in active labour and I think ~8cm dilated and then transfer to the delivery suite.
The plan changed because I found the induced contractions very strong and painful. They did not feel anything like the natural irregular contractions I had been having. So I ended up transferring to the delivery suite at about 2cm dilated within a couple of hours of having the gel.
I continued on gas and air until around 7cm dilated (I guess at around 8pm) at which point the contractions were painful enough that the gas and air wasn't enough and I had an epidural. Things were much better with the epidural although they did need to replace it and keep topping it up.
I was fully dilated and pushing by about 4am. I pushed for about an hour and then they decided to do an emergency c-section as the baby's heart was slowing on each push. It turned out afterwards the cord was wrapped around his neck a couple of times. The c-section was actually a really positive experience and it only took them a few minutes to get the baby out and the recovery hasn't been too bad so far.
So not traumatic - although I think it helps that the baby came out healthy so it is easy to forget any painful parts of the process. The pain was bad at times just before switching to gas and air and then later just before having the epidural and when the epidural needing redoing or topping up, but I suppose they don't call it 'labour' for nothing. So I think I would say be prepared to ask for pain relief including an epidural if you need one because it makes things so much more bearable. It doesn't make you a wimp.
You might want to check with your hospital about where you would be after they induce you. I was really surprised at how lovely the rooms were in mine and they only put you in a shared room if they have run out of the private rooms which they said isn't common.
Good luck anyway. It's all worth it in the end (I've just been up doing a feed of my beautiful baby).
