IUD HELP

Ava • A scoop of shitposting, a pinch of honesty; 100% random shit that comes to my mind *And some sex Q's

Anyone else get weird stringy discharge that's reddish brown, and it's in the outer bits of the vaj? I have an IUD and I assume it's all the buildup from periods that have not been or something. Please tell me if I'm wrong🙏
