Period question (postpartum)

Anyone else have cycles like this (is this “normal”?) I am on my 2nd cycle post birth (14.5m pp). My period onset is normal flow Day 1-4, day 5 it’ll be spotty/brown then be done by Day 6. Then, on Day 7 I get another wave of brown spotting with dark brown discharge. Is this just my cycle really cleansing out? Or is that an indicator of a hormonal thing? I can’t recall what it used to be like since the last period I had was Nov 2019. Please share your thoughts!
