Have mercy! It looks like I lost my whole cerclage over the weekend. I woke up with black thread in my pad. I guess they couldn't use the regular thick thread bc my cervix was thin from trauma with my past pregnancies. No one told me this so I had no idea that was my WHOLE cerclage. My length is still at a 3.1 no funneling so baby is holding. Looks like progesterone and bed rest and hope for the best. I can't believe this!
