Still postpartum bleeding at 9 weeks?

I am 9 weeks and 3 days pp…. I am still bleeding on and off. I thought it was done (again) but had some blood overnight and still this morning.

Is this normal? I will go 3-5 days of nothing then a day or two of bleeding and then we circle around again. I am so over this! I didn’t tear with this birth so I don’t get it. With my first I stopped bleeding at 6 weeks +/- and I had a second degree tear. Any suggestions on what I can do?

I am on the mini pill but have been for 7 weeks and have not missed any or taken any late. So I don’t think that is it.
