I underwent Cervical cerclage on week 13. Currently I am on week 17. While inserting the nightly projesterone last night, i tried to push it a little higher as i could barely insert my finger. And, I noticed I could feel my cerclage some metallic or hard plastic thing ! Like right there at the opening of the vagina with just 3/4 of the finger. Is it possible to touch the cerclage that easily just with 3/4 of the index finger? Anything to worry about?
