How soon after delivery did your get your period?

I am curious on when you ladies got your first period after delivery....

This may be TMI-

I am currently 4 weeks PP and up until today my discharge had been a pinkish brown color which had been thick and mucous like. Well today it has been deep blood red with no mucous. Just pure blood and blood clots. The flow is also heavier than it has been in the past 2 weeks. Could I be having my period this soon?
