A little worried

Okay this may be a dumb question & im just a super paranoid person so someone please reassure me. When I was checking my iud strings I slightly traced/rubbed my iud string because I found the strings coming out of my cervix and traced it down to the end of the string to check the length. I always see where people say how easy you have to pull for them to come out so I was worried I may have pulled it a little when I was doing this?? What do y’all think??
