My waters broke at home at my contractions ramped up immediately so we phoned the hospital. The said to have some breakfast and a shower then head in. We left about an hour later when my contractions were 2-3 minutes apart. DD was born 6 hours later. Her arrival would most likely have been a lot quicker (I was at 9cm in just over 4 hours of my waters breaking) but she was posterior.

Discuss it with your midwife/OB as some hospitals have different policies. For example, my OB wouldn't allow me to go in the bath once my waters had broken. The shower was fine though. Some hospitals will listen to you having a contraction over the phone to determine where you're at.
