When did you start dilating?

Cam • My sweet little pea is here! Born June 1, 2016 🎀
I'm 37 weeks and my cervix is still closed. Hoping I don't need to be induced. I see women start to dilate now then have the babies at 40+ so I'm kind of nervous lol. Just curious as to what week you all started dilating and when the baby was born?
