Bleeding 8 weeks postpartum

My bleeding stopped around 4 weeks pp I had nothing for a week or so then had 2-3 days of light bleeding then it stopped again and it has now started around 7 and a half’s weeks pp and still getting some blood now at 8 weeks post partum, it’s not heavy just seems to be on the tissue. Is this normal? With my other 2 children the bleeding stopped around 3.5 weeks and never returned. I am also on the cerelle pill and breastfeeding this time so not sure if that’s related?
