IUD Strings

So I've had my IUD for about 2 months now and at 1 month I had a checkup and my doctor said my stings were there. She told me I need to make check every so often that my IUD is in place. My doctor also said my cervix/unterus is high up. So when I've checked I couldn't feel them, I'm not worried it has moved or anything because I have not had pain or abnormal bleeding. Do any of y'all have this problem as well? also what do the strings feel like?
