COPPER IUD SIDE EFFECTS?

I got my IUD a week ago, I had some sort of spotting for 2 days after that, then everything was normal (basic discharge, no pain at all) then for 2 days now I feel like I have some discharge with some blood in it, not bright bright red but some blood, the discharge doesn’t smell, but it’s soooo itchy! My doctor gave me an appointment in January but what do you think? Have it happened to you after having a copper IUD? Do you think it has to do anything with it anyway? Thank you guys!
