My labour was fast and furious (3 1/2 hours). I went from 5cm to 10cm in 25 minutes and had a 25 minute second stage. Way too fast for my enphorines to catch up to my body.
Like it's been said don't focus on numbers. Progress is progress and don't let them force you into thinking that if your body is going a bit slower than 1cm an hour you won't get there. Keep going because your body knows what to do and will get there. Best of luck.
