8days late ?

TrulyBlessed
I'll start by saying my AF is very regular and has been for 3yrs now ! This month my AF was 8 days late then she appeared ! My AF is usually heavy with a decent amount of clots this month just very light basically just spotting with lots of CM ? I usually soak thru a tampon within an hr or 2 this month I'm just wearing a panty liner and there is barely anything there when I change it ? It honestly looks like more CM than blood ! Anyone ever experienced this ?
