Kyleena IUD Strings

I got my Kyleena placed in early September and then had the placement checked the same day with no problems. Since then my period has been regular and light with the usual miserable cramps. I never checked my strings since this is my second IUD I hadn’t really thought about it until now and I can’t feel them. My period ended about a week ago and I’ve had some on an off again cramps.

I’m torn between making an appointment to make sure everything is good and just trusting that it’s fine since I’m not really experiencing any other weird symptoms but some advice would be great!
