Having had both i can say that the induced labour straight away started with contractions that felt the same as the spontanious labour at around 5-6cms dilated. So it was really hard and fast the whole way through. Whereas with the spontanious labour, i eased into it therefore i got used to the build up as it was slower and less intense. i hope that makes sense! So if you can i would definatly just wait and not be induced.
