Cervical length. The length of the cervix is the distance between the internal os and the external os. First-trimester cervical length is greater than 5 cm. The cervical length decrease to less than 34 mm at 28 weeks' gestation. In patients who have had multiple gestations, the cervix is notably shortened.
Cervical length during pregnancy is sometimes associated with preterm labor â labor that begins before week 37 of pregnancy. If you have a short cervix, you might be at increased risk of preterm labor and premature birth. The earlier premature birth happens, the greater the health risks for your baby.
