When Do Obstetricians Check for Dilation?

Pelvic exams in pregnancy vary depending on the doctor and the practice. Your cervix's dilation and effacement might be checked every week starting at week 36 (or earlier!), or not until week 38 or 39, or your OB might not do a vaginal exam until you're in labor.

When does the Obgyn start checking your cervix?

Beginning at 36 weeks, we will check your cervix for signs of impending labor.

What week do you usually start dilating?

When do you start dilating? You generally start dilating in the ninth month of pregnancy as your due date gets closer. The timing is different in every woman. For some, dilation and effacement is a gradual process that can take weeks or even up to a month.
