I had a pprom last year at 26 weeks due to unknown reasons. Now I am 23 weeks pregnant and this time I had a cervical cerclage placed at 17 weeks as a precaution. Now in my latest anomaly scan it showed u-shaped funneling of 1.5 cm with width 1 cm. Cervix length is 2.3 cm. I am on weekly proluton depot 500 mg shot, duvadilan 2 times a day and duphaston. But my doctor suggested for either hosp admission or complete bed rest. What is the best option? And will the funneling stop with strict bed rest after few weeks? Are there any chances for the cervix length to increase?
