1, just got a BFP for my 2nd today!! If you have any specific questions I'd be happy to answer them, other than that I also have my birth experience typed out if you'd rather read that. I don't know if it was cleaner as such. I had to have my waters broken before I got in and obviously when my DD was born there was blood in the water which they let out nearly straight away before delivering the afterbirth but the experience was amazing and I really felt it helped with the pain. I didn't get into the pool until I was 9cm - I got into the bath early on which really slowed my progress so definitely go with the nurse/dr recommendations of staying upright as much as possible prior to getting in!!
