I wasn't really induced, but with DD2 I'd had 18 hours of prelabour and a hindwater leak before heading to hospital. I was only 1-1.5 cm dilated when my waters were broken and she arrived 4 hours later. I was surprised at having such a long prelabour as I had a quick birth with DD1. Everyone had been telling me to head to hospital at the first niggle this time but I ended up having loads of time and still needing help.
