Brown discharge 3dpo - ovulation or IB?

Ovulation spotting at 3dpo?

I know for sure when i ovulated and I’m 3dpo. Had brown spotting earlier. Could it still be from that? Or has anyone had IB super duper early? Any experience is welcome here lol.

I have never ever had mid cycle spotting (never had ovulation spotting) before, unless it was IB.
