Postpartum period

Mia

Ok everyone i need some help! I believe i had my first ppp 3 months after the birth of my baby. so nov 2-6 i bled. It wasn’t heavy or anything but i bled like constant like a period..so my period was due 5 days ago. I exclusively breastfeed with my baby but at work my baby gets stored breastmilk along with formula sometimes. is this normal for my period to be late ??
