You might want to ask this on the pregnancy 18-34 forum, only because there are so many more members, I know what a cerclage is, but I'v never had to go through it so I can't help. Let us know how things go, I think tarrah on this forum just had one put in if I'm not mistaking maybe she can help.
i had one on nov 3rd but that was bc i lost twins in march but when i was told i needed a cerclage my cervix was 1.3cm a week later i gave birth w/o the cerclage my cervix hasn't opened up yet this time bc i had a stitch put in at 13 wks to prevent that. i wasn't told how the measurements work with that.
i had lost my son at 20weeks nd then lost my daughter at 22weeks i am now pregnant with my 3rd child nd will be needing a cerclage placed in i am now 12weeks4days nd will be having the cerclage placed when im 13weeks im very nervous nd just hope it would work its my only hope
