Is Brown Vaginal Spotting Normal After Finishing A Period?

hi! I am 37yo. Currently breastfeeding first child who is almost 8 months old. Have hx of pcos. 1st period postpartum was 1/30/10 for 6days, very heavy. 2 wks later, I had brown spotting for about 3 days. Last week, I had more brown spotting and some blood for 3 or 4 days. Is this normal?
