So you can technically get pregnant at any time of the month, so why throw in a couple placebo pills? What do they do exactly, and can you get pregnant during that week of taking them?

Answer 1

The placebo pills are just there so you can keep up a regular habit. If you do something every day, you won’t forget to do it. If you do it only every few days, you probably will.
