Try not to feel defeated. I had my 38 week appt on thursday and wasn't dilated at all. Zip. Zilch. 70% effaced. Contractions started yesterday morning and I still wasn't dilated when I got to the hospital so they sent me home. 2 hours later I was back at a 2 and within ONE hour I was a 10 and fully effaced. Had a VBAC at 6:18. It can happen way faster than you think. Stay positive.
