With my first pregnancy my cervix stayed closed until the morning I went into labor. By the time I was contracting regularly with plenty of pain, I was 2.5cm. This was exactly at 40 weeks, and I stayed in active labor until I delivered the next morning.

I just had one of my weekly 9th month appointments and found out I'm 2cm dilated!!! I'm 37 weeks tomorrow.

If you found out you were dilated before active labor started, how much later did you go into labor?
