Spotting question, help please!!

So I feel so dumb asking this, but for the last 3 days I have been kinda spotting...either just when I wipe after going to the bathroom, and its only mixed with sticky cm, or I only will have pink blood on my finger after I check my cervix...other than that nothing, I have put 2 tampons in today and nothing on either of them...I thought maybe it was af starting early, but nothing else is happening...any help or insight is appreciated...af is due in 3 days, so the spotting started 6 days before af..most of my periods start with a normal flow..never spotting even at the end. Thanks and sorry if this is a dumb question..just curious on what the hell my lady bits are up to.
