If you are unsure whether you have taken your contraceptive pill or not, it is generally recommended to continue taking the pill as usual. However, it is important to use additional protection, such as a condom, if you engage in sexual activity in the next week. Continuing to take the pill without a break between packs has been studied and shown to be safe for up to three months in a row. There is no need to worry about extending the use of the pill beyond the usual 21-day cycle.
