It may be possible that you didn't completely finish postpartum bleeding yet. I bled for a long time after my son and I'd stop bleeding for two or three days then start again. I don't remember exactly how long it lasted, but it was a while. It might also have something to do with your birth control...have you taken that kind before? I've never taken birth control so I don't know how all those affect you and stuff. But I know my bleeding was for a while and on and off, some light, some heavy until eventually it stopped altogether.
I guess it could be possible that I didnt finish my postpartum bleeding, I never with my other kids bled for this long, it is just disgusting. I have never taken this birth control before so it may be the birth control to. Thanks for the input.
If you hadn't taken the birth control before it might be causing it. If I were in that situation I would stop the birth control and see what happens. If it stops then you know it's the birth control. Good luck :)
