Ive been on birth control pills for quite a while, almost a year. I do skip my periods every so often. These past 2 months i skipped my period but this past month i tried to skip my period again but i keep bleeding every other day. At first it was dark/brown blood & it was during what was suppose to be my placebo week & now its my 2nd week day (almost the end of my 2nd week) & im still bleeding. Its pretty light & its a lot lighter in color. Is this normal? Is this still just break through bleeding?
