Period Calendar

Our official period planner is the perfect tool for knowing when you are starting your period. Two - three days before you think you are about to get your period, you can start wearing your BFF Period Undies, so if you are caught off-guard, your BFF will have your back! Once you get it, continue to use your BFF Period Undies with your favorite pad and or tampon. Depends on your preference and how heavy you are.
