What Happens If You Take Two Birth Control Pills in One Day?

Taking two birth control pills in one day typically won't cause serious harm but may increase side effects. This can happen if you missed a pill the day before and need to take a makeup dose, or if you accidentally took an extra pill. Common side effects include nausea, breakthrough bleeding, breast tenderness, and headaches. The extra hormones can temporarily disrupt your cycle, potentially causing irregular bleeding for a few days. If you took two pills by mistake, continue your regular schedule the next day and don't skip any pills. Contact your healthcare provider if you experience severe nausea, persistent bleeding, or other concerning symptoms lasting more than 24-48 hours.
