Brown spotting during ovulation!?

So I’m on my second cycle after my miscarriage, I had a dnc and exactly a month later I got my period, going off that period I should have just finished ovulating but yesterday I got light brown spotting that over night turned into dark brown spotting (a very small amount maybe the size of my little finger finger nail on a liner)

Is this normal after a misscarrage or dnc?

Could it be implantation bleeding, Or is it to early for that?

I’m only sure I ovulated because I had discharge a few days before.
