In this video, Dr. Manjeet Arora, Consultant Obstetrician and Gynaecologist at Cloudnine Hospital, Kailash Colony, New Delhi, explains the importance of cervical length in pregnancy, especially for those with high-risk factors like twin pregnancies, previous preterm births, or second-trimester miscarriages. A normal cervical length helps ensure that your baby stays safely in the womb until full term. Dr. Arora discusses what's considered normal, when it's a cause for concern, how it's monitored using transvaginal scans, and the available treatments—like progesterone or cervical cerclage—to reduce the risk of preterm labour.
