Postpartum bleeding question- might be TMI

FTM here 👋🏻

I am 5 weeks PP. my discharge this last week has been the white/tan lookin stuff. But earlier this evening it started getting dark brown again and the amount is getting bigger each time I go to the bathroom.

Is this normal for it to go back to being dark brown? Is the amount okay? My liner is about a quarter full of it when I go about every 2-3hrs.

Thanks in advance!
