Spotting for 2 days so far. Good sign or bad?

So I started spotting very little yesterday. I was dpo12. It was pink/red with some brown. Not much. Only when I wiped on TP. Now today’s DPo3. Same thing. Spotting. I’m expecting my period tomorrow. Does anyone have spotting for more than 2 days and lead to BFP?? I feel fatigue and bit of nasous
