discharge help

last period was around christmas. i’ve had an IUD since February (tho i need to get the strings checked bc i can, for the last few months, feel them when i barely stick my finger in as well as my ex saying he could. i got checked for any STIs back in october after having a UTI and when the pee came back they said it was all fine. i haven’t had sex since then. my discharge has just been super off lately:( it’s like light brown someTimes pinkish. some days it’s more like jelly almost. i’m not itchy.
