The two IUDs we have available for teens are Mirena and Kyleena. Kyleena is a slightly smaller IUD and contains fewer hormones than Mirena. However, smaller IUDs can sometimes cause more breakthrough bleeding (spotting between menstrual periods) than the larger ones. Both Kyleena and Mirena are great options for teens. With both these IUDs, your period may become shorter and/or lighter. Some people will eventually stop getting their periods at all. We encourage you to make an appointment to further discuss your options with a medical provider!
