Need advice: Cervical length 2.7 cm at 23+4 weeks – cerclage or observe? Hi everyone, I’m 23w4d pregnant and need some clarity about my cervical length. Previous scans (abdominal): NT scan (12 weeks): Cervical length ~3.2 cm (abdominal) Anomaly scan (20 weeks): Cervical length ~3.2 cm (abdominal) Current scan (transvaginal): Multiple measurements: 2.82 cm 2.70 cm 2.66 cm 3.09 cm Final TVCL: 2.7 cm Internal os: closed No funneling On vaginal progesterone My doctor said this is a significant drop of 0.5 cm and recommended immediate cerclage. However, I’m unsure because: Earlier measurements were abdominal, which tend to be longer than transvaginal, So I’m not sure if this is a true “drop” or just a measurement technique difference. My questions: 1. Is 2.7 cm at 23+4 weeks considered high-risk? 2. Is it normal for abdominal measurements to differ from TV measurements? 3. Should I get a cerclage immediately or take a second opinion from an MFM? 4. Can the cervix remain stable around 2.7 cm until 28 weeks? Any experiences or expert opinions would really help calm my mind. Thank you.
