Did your doctor recomended having a cerclage as prevention method? I am having cervix cerclage next week at 13w3d. Doct told us today that usualy after a twin <a href="https://glowing.com/glow-fertility-program">ivf</a> pregnancy the cervix is more likely to open before 20w causing mc or preterm labor. So the cerclage before 20w its the better method to prevent it. And the risk was higher if you had a mc previously (wich i had last july). Wondering what you other twin momas doctor told you?
