Paraguard coming out?

Darcy
So I went in at 2 pm on 6/28/16 to get the implant. Went okay, but my doctor didn't explain anything to me...at all. Not how to check the strings or anything. He finished the implant with a slightly concerning statement "that was easy...too easy". Super uncomfortable sitting and walking immediately after but I though was normal. Not even 6 hours later while using the bathroom I felt something down there. My mom used gloves and checked and said she felt plastic. To the ER I went. They did an exam and couldn't find it until she used her fingers and it was pressed against my vaginal canal. Now it's sitting in one of those little pee cups on my dresser to take in tomorrow. What are the chances of it coming out again?
