3 weeks postpartum 👶🏼🤔😖

I’m 3 weeks and a few days postpartum and my bleeding had subsided for the past week. It’ll have me thinking I’m done bleeding bc I’ll just be wearing a painty liner all day with light brown spotting then I wake up go to the restroom and have a random streak of red blood and sometimes bright red spotting. And it doesn’t seem to be going away 😩😩 is bright red spotting normal during postpartum???? I thought I’d already be done bleeding by now. This is my first btw!
