Period after MC

Mirna • MC 6/25/19 🌈 👧🏼 6/4/20

We had our MC June 24th. I had my D&C June 27th. We were 12 weeks but baby stopped growing at 8-9 weeks. I am about 3.5 weeks post D&C and just last Wednesday I got brown discharge like I do 2 days before my period but nothing yet. I still have the brown discharge on and off and it’s getting lighter. There is no odor or concern for infection. Has anyone had this happen? When did you get your period?
