Spotting after miscarriage

Carolina • Mommy to two little girls
I had a miscarriage at 12 wks on October 28th and had my period about 12 days ago. It was a super short period, only like 2 days. Now I'm spotting a tiny bit, which is really confusing. I don't think it's implantation bleeding because it is a little too soon for that. Has anyone experienced this before?  Input would be highly appreciated.
