Any vaginal bleeding during the time you’re taking your active pills is called “breakthrough bleeding.” Any bleeding when you are on your break (placebo) week is called “withdrawal bleeding.” The pill works to make you not ovulate, so any bleeding you experience at any time is not considered your period anymore. Bleeding is also not an indicator about whether you are pregnant or not. Bleeding is a normal side effect of the pill. There is a 3-6 month adjustment period to the pill, but symptoms (including breakthrough bleeding) can happen at any time, even after the adjustment period.
