I'm 22 weeks along in my first pregnancy, and after a recent scan, my cervical length measured 2.9 cm. At the NT scan, it was 3 cm. Should I be worried about this change in cervical length, or is it considered normal?

Cervical length of less than 3cm measured between 20-24 weeks of gestation is associated with preterm births and favours vaginal birth whereas, cervical length of more than 4cm is associated with postdated pregnancy and increased incidence of cesarean section.
