How long was your first period after miscatriage

So
I miscarried my angel baby April 22, bleed for 5days and then 3weeks later started AF. It's been 12days and I'm still bleeding. The only thing is it started with mild spotting then light/medium flow. Hasn't been heavy or cramping. Has anyone else had this too. My doctor isn't concerned but I'm so done with my body being weird.
