Birth Control and Periods

Hey! Just a simple question that I can’t seem to find the answer to and not sure where to ask.

I’ve always have light cycles ever since I started my period. Always been a typical thing. I started birth control in January and for as long as I can remember it always takes a day or two coming from the third week of pills to the sugar pills to get my period. Is this normal? I am just not sure what to expect and it’s been this way since I’ve started birth control. Usually two days then I’ll get it.

Thanks.
