I am about 21 weeks with twins! I saw a specialist 2 weeks ago (at 19 wks), who did an internal US and let me know that my cervix was measuring 1.7cm. I suggested a Cerclage and he told me that it does not work with women having twins. I've seen on a few posts about women with twins/triplets and getting the cerclage. Is it possible to do with twins? Will it work? Are there many risks involved? Does anyone think I should get a second opinion?
Any advice would be helpful
