Postpartum bleeding

How long did you bleed after baby and how heavy was it? I had my second baby two weeks ago. The first two days after I had super heavy bleeding then it almost went away. Over the past two weeks though it’s been so inconsistent like some days I could get away with a panty liner other days I need a heavy flow pad. I know you can get a heavier flow if you’re particularly active one day but I literally haven’t done anything but put around the house since she was born so I’m not sure why all of a sudden I’ll have such a heavy flow. Also I’m breastfeeding.
