How much is too much?

L

I got my copper iud on the 28th bleed for four days then for one week I was fine. I started to bleed again on the 10th and I haven’t stopped since. It’s actually getting worse everyday to the point I’m changing out a pad about every hour because it over fills the pad and I start staining. Today I had a two hour class and I stained my pants even tho I got up in the middle of it to change my pad. I’m cramping but nothing I can’t handle or ibuprofen can’t fix. I know I’ll have bleeding but is this too much?
