A member asked:
Is 3cm the normal length for your cervix at 21 weeks?
A doctor has provided 1 answer
Not normal: A 3 cm cervix at 21 weeks is not what most women's cervix measures, but it has been deemed sufficiently long to herald a risk for preterm delivery, which it does, when the cervix is shorter than 3 cm at that gestational age.
