Skipped Placebo Pills

so i’ve been on my birth control for more than a year, i decided to skip my placebo pills (therefore not causing the withdrawal bleed) for the first time & everything was fine and i started my new pack, but here i am midway into week 2 or 3 of my pills and i am having bleeding. it’s not super heavy it’s almost like the first day of a period & this is the second day it has been happening. I’m not sure if i messed something up or is this normal? Does anyone have any advice?
