Can you switch the day you start your birth control pills?

Yes, you can. To change the day you start your Birth Control pills, you will cut short your placebo/sugar pill week or pill free week. For instance, if you normally start the new pack on Sunday and want to start on Wednesday, you'll take your placebo pills on Sunday, Monday and Tuesday, discard the old pack, and start the new pack on Wednesday. As long as you don't go more than seven days without an active pill, you will have no interruption in protection.
