anxious mummy

I lost my baby rescently due to an incompetent cervix. I was just wondering if anyone has any success stories with having a cerlage placed in, and how far you managed to keep the pregnancy going, if it worked,or not worked, unfortunatly this is something i now have to consider if i am to try for another baby in the future. I am just very anxious, and scared, i dont want to go through this type of pain, and heartbreak again.
