Waters broke at 7:10pm, arrived at hospital at 9pm (first contraction happened in car to hospital, third one happened as I walked into hospital), was 4cm's when arrived and by 11pm I was 10cm and starting pushing, 11:55pm my son was born.
According to my notes I was in active labour for 3 hours 7 minutes (Including delivery of placenta).
(I went to hospital before my contractions kicked in because I was high risk, you should normally wait until they are 5 minutes apart).
