Cerclage after previous preterm birth

Ja

Has anyone had a cerclage to prevent preterm labor? What's your experience and did it work?

I'm 15 weeks along with baby #2. My first was born at 31 weeks after sudden onset preterm labor at 30 weeks. I'm being watched carefully this time around since there was no known cause for me to start contracting, and a cerclage is really the only option for me if I do show signs of early labor again. Any words of advice would be much appreciated ☺️
