I was induced due to gestational diabetes, I too was worried as I'd heard plenty of horror stories and my previous delivery was an emergency c-section so no idea what labour actually felt like
Admitted Wednesday mid morning, pessary in at 2pm, I did have to have gas and air for this BUT it was my first experience of gas and air which obviously was hilarious the more I had, 24hours with the pessary in-situ, no pains at all, just boredom, after removing pessary I was examined and they said they didn't think they would be able to break my waters and I had to wait to speak to the consultant for next plan (possible c section due to previous) at nurse change over, new nurse came on, examined me and said she thought my waters could be broke and made plans for doctor, he came and agreed. I think by this time I was having 'pains' - which really weren't but I thought they were lol little did I know 🤣.
I was transferred to labour suite at 10.30pm, hooked up to monitoring belts due to previous section, he came and broke my waters, then they started the drip THEN it all happened so fast, contractions straight away, the midwife advised epidural, they came and did that. I went from 3cm to 10cm in about half hour, still tooting on the gas and air. TBH I thought I needed a poo cos all the pressure was in my bum and I kept thinking if I can get this poo out I can concentrate on labour - obviously I was smack bang in the middle of labour unaware. The midwife examined me and said the epidural was a waste as I was fully dilated and I could start pushing. My little girl was born 4 pushes later!!
Afterwards I found out she was back to back, the reason why I thought I needed a poo
It was a strange experience as at first it was long and drawn out and boring but as soon as the labour proper started it went so fast, labour suite at 10.30pm, baby born at 3.20
My advice is to think every single delivery / labour is different, go with the flow, it does hurt - it hurts like a shitter but you'll forget, 7 months later I'd do it again (if I weren't too old). Good luck you will be fine!!
