Paragard iud

Tee

So I got my paragard iud inserted a month ago and ten days after I got my period and lasted for 5 days so it was all good so it’s been naw around my ovulation window so for the past four days I been having heavy bleeding I change my pads like four times a day and I pass small m blood clots, does any one understand what is happening to me and why am I bleeding and I still have 12 days for my period ???
