Preterm labor can be diagnosed only when changes in the cervix are found. Your obstetrician or other health care professional may perform a pelvic exam to see if your cervix has started to change. You may need to be examined several times over a period of a few hours.
A short cervical length between 20 weeks and 24 weeks is the best predictor of preterm birth: Length less than 1 cm: Mean birth gestational age 32 weeks. Length less than 1.5 cm: Mean birth gestational age 33 weeks. Length less than 2 cm: Mean birth gestational age 34 weeks.
