Disappointing to see another woman that hasn't had contact with their midwife to explain all this, I'm sorry to hear this OP. As a starting point if your trust uses that bloody app there might be a link to leaflets that you should have had about induction on there or they may be on your trust's maternity services page.
For me it was turn up, wait, pessary, 8 hourly monitoring, 24 hours later check on the cervix when removing first pessary, bung in a second..when you get to 2cm they put you on the list to go to delivery to have your waters broken and the drip (although looking back I don't know if the drip was actually compulsory straight away like they seemed to hint it was).
If you're lucky the pessaries with start you off so they'll get you down to delivery without too much bother. Ask loads of questions, unless you get a really good one they won't bother telling you half of what you might be worried about. You can have gas and air for examinations, they probably won't offer it.
Take everything with you as if you're in labour as I think from reading on here most places don't let you leave hospital once you've started the induction process although mine did let me go out round the grounds etc as long as I was back for my turn on the monitoring.
For us if we are induced we have to go on delivery suite not the midwife unit but they did have one pool available so you could ask the question. I had an epidural as I had the drip so I didn't get any info on that.
Did they say why you're being induced, I guess you must have seen a consultant if the decision has been made without you seeing a midwife? There's loads of threads on here about inductions so I would trawl through them and write down as many questions as you can, give them to your birth partner to be in charge of making sure you know what's happening and why. I believe in trusting medical professionals but they can be absolutely crap at explaining what options and considerations you have. Have a look at BRAIN decision making too.
Fingers crossed you get one pessary and that gets you going by yourself and all what I've posted isn't of any use 🙂 you will be fine, it may not always feel like it but you will!
