Starting to get worried about my postpartum bleeding?!!

I am 8 weeks postpartum and I am still bleeding! I started the birth control pill at 3 weeks postpartum. I decided to skip my first break week to hopefully stop the bleeding, but that didn’t work. So half way through my second pack I decided I should probably have a break week and see if it stops the bleeding the re starting the pill again. Well it’s day 3 if the break week and the bleeding is getting heavier and I’m now passing clots, weird brown tissue like clots? Is this because it’s a withdrawal bleed? Or should I start to worry? Iv been starting to feel dizzy a lot and I don’t know if it’s because the amount of blood I’m losing for a prolonged time! Am I becoming anemic now?
