IUD??

Is

So I got my iud placed August 12th ( just over 3 months pp) and I have been bleeding ever since. It's not super heavy bleeding, most of the time it's just spotting. Is that normal??? I have a follow up appointment in November but I don't know if I should try to call and make an appointment closer? Someone said they could have placed it wrong or something. I just want to know if anyone else has had this
