Why is my period early if I'm on the pill?

This is my first month taking the birth control pill. I started taking it the Sunday after my last period. My pack says I should start getting my period this Sunday. I have some light bleeding now. If my pack says I should get it next Sunday then why have I started to bleed now? Is it because it's my first month and I'm not use to it or what? Help please!

ok i think you're a bit confused. how the heck can the pack of birth control tell you when your period is going to start?
there is no specified day that you get it.
you typically get it between 2-4 days after you start the sugar pill reminder week.
so where are you in the pack?
