PP bleeding... what is normal?

Becky • Mom of 2 💕
I'm 4 days PP with my second. I remember bleeding for awhile with my first but I don't remember what it was like. I'm still bleeding like a semi light period but it's still very red. Online it says you shouldn't be bleeding bright red at 4 days? How much of this is true? I also had stitches in 3 places...
