My first was also an induction and I went from 1cm to full very quickly. like you. My 2nd was very different. pain was easy to tolerate and my contractions never got closer then 5 minutes. They just got longer. When I rang both times to say I was coming in and when I got there with both DD2 and DS I knew that the MW thought I was not close, like I said in my other reply DD2 was here under an hour and DS under 2hours.
