I started the induction process with the pessary (the one that's meant to be in for 24 hours) put in when 11 days overdue on the Friday morning, and my baby wasn't actually born until the following Tuesday morning. The pessary didn't really do anything for me and my waters didn't break, which meant that I was bottom of the priority list for a move to labour ward despite being 2 weeks overdue by the Monday and some blood pressure concerns towards the end of my pregnancy. We eventually were moved to labour ward on the Monday evening, but were being told from the Saturday onwards that the move would "definitely be today", "definitely soon", etc, which just made the waiting worse, and I would have been much better mentally prepared if I had been told from the beginning that it was possible that we may have to wait for a few days. The lady I was sharing a room with in the antenatal ward had been waiting for 5 days with her previous pregnancy, so I would definitely be aware and prepared that there could be a wait if nothing happens with the pessary and, as others have said, take lots of food and things to entertain you, or even go home if you can until there is a room on labour ward available.
Once on the labour ward my waters were broken by the doctor as the midwife couldn't manage it, and I was put on the drip. I found the waters being broken to be unpleasant but manageable, but unfortunately there was meconium in the waters from the beginning as the baby was distressed by them being broken. After reading advice on here and from my MIL who was induced, I asked for an epidural before being put on the drip, but the midwife was reluctant as she said it could slow things down, so I agreed to start the drip without one and see how things went. I actually found the contractions to be not too bad, and coped with a TENS machine and gas and air, and found that mentally imagining a balloon of each colour of the rainbow in sequence being blown up and floating away helped (and starting the sequence again when the contractions were lasting longer!), which was another tip I read on here. I also found that being on the birthing ball or stool made a massive difference, and things were far more painful on my back on the bed. I think I was quite lucky with the contractions though as it sounds like they are far more painful for some people, and I also only got to 6cm so it could have got worse if I'd got all the way to 10cm!
As the contractions progressed there was concern that the baby's heart rate was dropping with the contractions, and we were advised to have a Caesarean when I was 6cm on the Tuesday morning. We went quickly into surgery and the Caesarean went well and safely delivered our beautiful boy. We both had an infection (possibly caused by the meconium) and needed antibiotics in hospital for another 5 days, but by the time he was a week old we were both happy and well at home.
All in all it wasn't a pleasant birth experience and I wouldn't be keen to be induced again, but I got through it and it ended with a safe delivery.
