Period/bleeding after miscarriage

Charlotte • 👼🏼30/11/19💔 expecting our rainbow baby due 30/11/20🌈❤️

Just looking for some advice please.

I had a miscarriage 30th Nov and then negative hpk 17th Dec.

I had ewcm 24th Dec and a positive opk so took this to mean I was ovulating however since 27th Dec had brown bleeding when wiping (very very light). I wondered if this could be a period however it is not pink/red?

Thank you in advance xx
