TMI?? Spotting After BM

For the past 2 days, when I go to the bathroom after a BM I have some light spotting. Not enough to use a pad or anything like that. Just enough to notice when I wipe then it's gone. I am 9 DPO and AF is due in 5 days. Is this a normal early pregnancy sign or do you think my period is about to start? I have never had this before.
