This is a study to see if the progestin-only birth control pill, Slynd, affects bone health.
Slynd is an FDA-approved birth control that is 98% effective at preventing pregnancy when taken correctly. Some birth control can affect bone mineral density (the amount of calcium and other minerals in your bones). Because of this, the company that makes Slynd, Exeltis, is researching the potential impact of Slynd on bone mineral density, especially in teenagers. You can choose to either take Slynd or use non-hormonal birth control during the study, such as condoms, abstinence (not having sex), or a copper IUD.
