Just had my first. Had been cleared for a water birth in a birth centre like your first birth, arrived to deliver and had high blood pressure, protein in urine and baby's heart rate was high so we had to take ourselves to hospital (no issues throughout pregnancy even a week before). I was put on hypertension medicine and then started vomiting a lot from the pain, filled three sick bowls in one go, then given anti sickness medication.
I had planned not to go for an epidural but was exhausted after the multiple trips, worry about the baby and even with the adrenaline prob after a sleepless night. Labour slowed down and was almost given the oxytocin drip but it then picked up on its own. I was using a TENS machine and gas and air but at 6cm felt too exhausted for the pain to get worse so decided on epidural.
Epidural then failed the first time (be aware to ask for it early, it takes about 15 mins to put in - feels like longer and you have to say when you're starting to have a contraction so the anaesthetist can stop and you stay as still as you can, bent forwards over a pillow sitting up on the side of the bed. Would be much easier earlier in labour). First epidural failed so I was scream-sobbing into the gas and air.
They then redid it which took more time but it was honestly amazing! DH left me for 10 min (I told him to go eat, day and a half in) making a lot of noise in pain and came back to me lolling on the bed smiling puffing on the gas and air saying what an idiot I was for not wanting it.
I could feel the urge to push and the OBS was saying I was pushing really well with it. Apparently my body really wanted to give birth but baby didn't want to come out. Ended up with suction cup 'kiwi'(?) delivery and episiotomy which I was grateful to have the epidural for. Delivered on my back in stirrups which was very different to how I'd planned to be upright, forward, open etc but I just felt completely exhausted and by the point they wanted to use the suction cup, baby's heart rate had dipped.
No issues at all healing from the episiotomy, I took it easy after birth and have healed well. Also no issues being 'with it' or bonding with my baby because of the epidural, which I'd been worried about, and no issues with my back. They put in a catheter at some point while I was in pain because I'd said my bladder was painfully full but I didn't think I could get to the toilet with the contractions I was having being so painful and close so I'd actually asked if they could just put a pad on the bed for me to go there (desperation!). Catheter was honestly great, no issues and took a lot of pain and pressure away too.
I didn't get my plan A water birth and as they suspected possible late stage preeclampsia I don't think I'd be allowed to try it in a future pregnancy either. Part of me thinks it would be interesting to try for no epidural next time to see if I can make it but DH and I were just saying today what's the point really especially if it would likely be a hospital birth in a labour ward anyway.
But honestly only positive things to say about the hospital experience, and I'd gone in dreading the cascade of interventions and assuming I'd be pushed towards a C section. Possibly if I'd been more relaxed labour could have gone a different way but the hypertension, protein in urine and baby's heart rate all being a concern first, I was just thinking I wanted him delivered safely ASAP whatever that looked like (and TBF that's what my birth preferences said as well).
