withdrawal bleed very light

my withdrawal bleed was really light this month, a lot lighter than it normally is. is that something to be concerned about? I definitely bled and it was definitely a withdrawal bleed but it’s sunday and I haven’t even taken my active pill yet and i’m done bleeding already, which isn’t typical for me. i’ve been on the pill for over 2 years. is this something to be concerned about? is it normal for the amount of bleeding to vary between withdrawal bleeds, even on the pill?
