I'm a STM who should know the answer to this question, but here I am anyway. My OB said I am dilating, but my cervix is still thick, so in all likelihood, I still have "time" before I give birth. I'm wondering if thinning the cervix is something that can happen overnight, or is something that happens over a longer period of time, like 2-4 weeks.
I'm not in a rush for LO to arrive or anything -- so this is not a "I want him out NOW!" post -- more out of curiosity.
