Period after miscarriage

Brianna • Mommy to an 8 year old boy. M/C 6/25/18👼🏻 🌈 7/9/19

So I had my MC a little over a month ago. I have just started to spot yesterday. Could it be my first period after my mc? (Its light pick/brownish and only shows up when I wipe) My hcg levels have completely gone down to zero so I know it isn’t any left over from that.
