Period after giving birth

Trisha

This is my first pregnancy. I had a c section and am breastfeeding. I started my first period 8 weeks after giving birth. For the last 6 weeks I have bled for a week off a week and so on. This last time I only stopped for 2 days before starting again. Sometimes heavy, sometimes medium last couple days of each cycle light. No cramps or anything just seems like I'm always on my period. Is this normal?
