If you haven’t had your period for a year and you’re not taking birth control pills continuously (without a break), you should make an appointment with your health care provider (HCP) to find out why. Your HCP will order a pregnancy test if you are sexually active and will also check your hormone levels. There are many different possible causes for amenorrhea (lack of periods) but the most common reasons are: pregnancy, hormone imbalance, or being underweight.
