postpartum bleeding?

Hello! I'm 3 weeks postpartum and I had my baby girl via C section. Initially I was expecting a lot of bleeding but I was surprised as I bled heavily only for the first 4 days of the surgery and after that it was light bleeding. Now after 3 weeks I still have light bleeding, though sometimes it's merely just spotting. I was wondering how long did you have your postpartum bleeding when you've had C section, and when did you get your period after that???
