Please help—postpartum bleeding

Hey! Was wondering if any other postpartum moms could give me some reassurance/advice. I am 9 days postpartum today & thought my bleeding was almost gone. It has been very light the past few days. Today it was more red and a little bit heavier (although still not saturating a pad or anything like that). Then this evening I had a small gush of red blood after breastfeeding. Now it’s back to almost nothing again. Does this sound normal? Or do I need to be concerned? Thanks!!
