Hi there,
Well my induction wasn't planned it happened (ironically exactly a year ago today!) because my BP was raised and they suspected pre-e so mine was slightly different to a planned induction as it was a little more rushed.
I went in and was given a sweep and the pessary at 6pm, by 8pm my df had to leave as I wasn't on the labour ward yet and was told he'd be called if things started to progress. From what I've heard if there's no rush to start labour they try you with the gel or pessary again after 6 hours but for me they didn't do that even though nothing had happened so at midnight they broke my waters (despite only being 1cm dilated!!) and put me on the syntocinon drip. Now like another PP I'm not gonna lie to you. I was told it was advisable to have the epidural with having the drip as it forces your body into labour unnaturally but I said no, even after much persuasion I said no. An hour and a half later I was having what it describe as one long very painful contraction. It just hit me so hard, there was no build up, no small pain getting stronger, it was just so intense and there was no real break in the contraction either. And I was still only 3cm dilated. I then begged for the epidural and they let me have it coz I was on the drip but then that meant I couldn't move off my bed which I think slowed my labour.
I then progressed ok and my labour was 16 hours in total, but baby's heartrate was a little stressed and after pushing for 45 mins they tried to use forceps and realised she was brow presentation and couldn't turn her (she was facing the wrong way and stuck!!) so I had to have an EMCS. I don't think the induction caused the EMCS but I do wish I could have moved more and maybe she may have moved position but all was ok and that's all that matters.
Definately take your hospital bag with you and be prepared for a long wait because if there's no medical rush they don't like to put you on the drip if you don't need it.
As for induction failing, I'm not sure it's possible for it to fail completely, they will just put you on the drip if the gel and pessary don't kick start things. Then if you fail to progress in labour they will just increase the drip if they need to, I'm not sure what the chances are of EMCS though but honestly they aren't as bad as you'd think if that does happen. It's a little bit scary because it's a rush to get baby out safely but from my experience the medical staff are all really calm and helpful.
I hope it all goes well for you tomorrow, keep us updated and don't worry too much about anything, I actually enjoyed most parts of it so much I'm doing it again soon lol!!!
