3 week long period

L. • Married 💍 1 girl 💜 1 boy 💙

I've had the paragard for almost a year and it's made me periods WAY heavier than they used to be but they've always last like 5-6 days. Except right now. I've been on my period for 3 weeks with no end in sight. I had a normal period at first and then spotted for 2 days so I thought I was coming off of it and then it came right back. Has this ever happened to anyone else with the paragard?
