I have hideous long labours too.
I have 4 children and was induced with 2 and had my waters broken with my 4th to speed things up. Gonna give you the lowdown on my experiences.
With our first, had to be induced at 40 weeks plus. A good old two days labour. Pessaries were useless. Was given I think 2 or 3, they're pointless. Finally after 36 hours of being in hospital and being monitored things started happening. It was a total of 48 hours labour from the first pessary to delivering but roughly 14 hours established labour.
Second child, my waters went after husband and I did the business at 37 weeks. Went to hospital but nothing was happening. Was kept in to be examined and monitored because of water loss. They said they would start inducing me the next day. They gave me pessaries to speed things up. Pessaries are useless. Again, had 2 or 3. So they decided to put me on the drip. Which is by the way, the worst thing in the world. It makes you have contractions non stop back to back and it's just awful. I was literally begging and crying for the epidural. But there was no anaesthetist available to do it. So I was just left in agony. I was on the drip for 6 hours and it did speed things up. But I would never have it again I think I have a low pain threshold as I couldn't manage it about five. They turn it up a point every half an hour to increase the medicine going into your blood stream to sored up labour. Trust me its horrific. That was 48 hours as well from the moment my waters went at the house until the moment I gave birth. Baby was born small at 5lb4 but healthy.
Third baby, was born at 39 weeks on the dot. Waters went in the middle of the night. Theres a theme happening here. I always go in the middle of the night. Or at midnight. Dropped the other 2 off at my aunts, got to the hospital and husband and I were told to go back home as I wasnt dilated enough. Went home and tried to rest and also do exercise and walking, clean the house. Anything to basically speed things up. Would have had sex to get the party started but midwife advised against it as my waters had broken. Finally that night couldn't take anymore got to hospital, was only 3cm and just said can I stay please. Got given pethidine which helped until 7cm. Then straight into the birthing pool which I highly recommend. That was a total of 36 hours labour but my easiest one. The pool was a dream.
Fourth baby born 2018, usual thing happened. Contractions went at night. In the middle of the night. Went to hospital. Again, hubby and I told to go home as was only 2cm
Spent the day at the house with my husband watching movies and walking around and going up and down the stairs etc. Nothing was working. Then at 7PM ish we decided to go collect the kids from our aunts as we had dropped them earlier. But on the way there I was having lots of contractions so decided to go hospital instead. I was 4cm so they kept me in. Wanted water birth, but second midwife who took over told me no. She had a bad back and wouldnt be able to assist me. I should have just asked for a new midwife but I was too polite and thought it would be rude for me to ask of that. That was 32 hours labour. Hahaha my quickest. The only thing that did speed things up actually was my first midwife took me out of the birthing pool to break my waters. I might insist they do that if they can when I arrive. I really, really cant do no more 2 labours. It's hard work so I definitely feel for you.
Currently pregnant with our 5th child. Would like things to happen naturally. Wouldn't want to go down the induction route as A, I cant handle the drip and B, pessaries are pointless. I'm 34 weeks now so really hoping that because it's my 5th, things will happen quicker and hoping i will also get the water birth.
I really reccomend it if you can.
Best of luck for your induction today , and a safe and happy, healthy baby and delivery.
