It is fine to be dilated indefinitely unless your water is broken. Many moms who have more than 1 baby can be dilated a few cms for months or weeks. This is why some OBs don't check your cervix until you are in or think you are in labor or if you are overdue and need an induction. That being said I wouldn't ask for an induction until I was over 40 weeks and drs should not induce without a medical reason before 39 weeks at the earliest. (L&D RN)
My doc doesn't check to see how dialated I am until 39 weeks bc it can change at anytime. Wish i knew tho, it's kinda annoying:( 38 weeks
I've been 3 cms for 4 weeks and I was with my last pregnancy as well.
