Do you Dilate Before Effacing?


Dear Midwife,
I am 32 weeks pregnant and I saw my OB a few days ago. I had been having vaginal and rectal pressure so she did an exam. She said that I was 70% effaced but not dilated. I always heard that you dilated first. Can you tell me if this is any indicator that I will go into labor sometime soon?


Nope, most first-timers and many other pregnant women efface before they dilate. And since women's cervixes come in many lengths, it is hard to say whether someone is 30% effaced or just has a slightly short cervix. In other words, I wouldn't worry, sounds ok so far.
