Mirena iud

So i got my iud put in on the 26th of december 2019 and i have been bleeding since nonstop and i want it to stop already... how much longer until it stops? I heard from 3-6 months but idk. I have to throw out most of my panties bc everyday i have a different flow and my panties get stained (i do use pantyliners EVERYDAY and sometimes even pads). I’m so sick of this🥺
