Constant bleeding with my cooper iud

I’ve had my iud in since July 19th if 2018. I heard that spotting and liver periods are normal for the first 3 to 6 months, but I’m still experiencing spotting all the time. I have my period for about 7 days, which is just heavy bleeding but then for the rest of the month I’m constantly spotting enough blood to where I can’t just use a panty liner I need a regular tampon. It’s really frustrating and I have no idea if this is normal. If anyone knows what this is about please let me know. I’m at the point where I might go back to the pill
