I was induced with PE with DD1 and labour was about 7 hours. Waters broken & drip.

Natural labour for DD2, labour was about 10 hours , but she was posterior and i had about 4 hours of strong regular contractions without really progressing. Once my waters broke she was born very quickly.

I think there are so many things that can effect the length of your labour. Like your baby's position and your head space. If my DD2 wasn't posterior i feel like i would have had a shorter labour. Maybe that was just wishful thinking.
