Postpartum period or random spotting?

Have had 2, 5-6 day windows of pretty light spotting. Some amount of red blood with it, but never enough to even wear a panty liner. They were about 26ish days apart so wondering if these were my first postpartum periods or just hormonal spotting or something...I did opks in between and never had a positive one. Baby is a year old now so getting impatient to see what my cycle returns to.
