Birth Control Newbie

Sabra • Teacher 🍎 Wife 💍 Dog mom 🐶
I'm on my first month of birth control and I'm to the last row of pills (they are white, my other ones are blue) are these placebo pills? Will they start my period? Do I have to take them? I'm so clueless and my doctor really didn't discuss it with me. The brand is sprintec by the way! Any help is much appreciated 😄
