I think your hormones could be off and you should see a doctor to help you get thru this and to get your hormone level back on track which will regulate your cycles again.
Hi there and welcome. Well, that is outside of normal. It is most likely due to hormones and their trying to rebalance. I actually had no period for over a year due to nursing and the hormones associated with that.
I would say that you need to talk to your doctor about this though. I know most women go in for their 6 week post baby check up. Have you had your post baby check up yet? And what did your doctor say about the bleeding? I would absolutely call and make an appointment.
Are you passing clots?
good luck
