Postpartum periods question

Amanda • 👧🏼 7/8/19 💖, 👦🏼 4/16/21 💙

Hey ladies, I got my postpartum period June 2nd (6.5 weeks postpartum with number 2), exclusively breastfeeding but he pretty much sleeps through the night since around 5 weeks old. My cycle length is normally 26-28 days long but postpartum with my daughter (child #1) I had one cycle length of 31 days. I’m now due for another period as I am on cycle day 33 and have had faint spotting off and on for the last two days and not an actual flow (not typical for me). Is this just hormones still trying to return to normal?
