Is it okay to go back and take the placebo pills one week into your new pack of birth control?

It's generally not recommended to go back and take the placebo pills after starting a new pack of Birth Control; doing so can disrupt the cycle and reduce the effectiveness of the contraceptive. The placebo pills are designed to allow a withdrawal bleed and should be taken as directed at the end of the pack. If you've made a mistake or have concerns about your birth control, it's best to consult with a healthcare provider for personalized advice.
