Cerclage string?

Ashley • Avoiding pregnancy. 3 losses (6, 16, 15 weeks). 1 earth son, Lincoln born at 26 weeks. Just turned TWO & doing great!
Anyone have thin black piece of string come out? My doctor never warned me about it could be possible so I called on call Ob and she said sometimes they stitch a bleeding site and that the actual cerclage is like 1/4 inch thick. Anyone have this happen?
