[Method] Hormonal pill, skin patch, or vaginal ring [Consideration] 
These are the most popular methods used by teenage girls. You must remember to take a pill every day at about the same time. Talk to your health professional about any side effects. Another type of hormonal birth control may be better for you if side effects are a problem. After stopping birth control pills (at the end of a full pack), you can become pregnant in the next month. The patch is changed every week, which you may prefer to taking a pill each day. The vaginal ring is a foldable, flexible ring of plastic that stays in the vagina for 3 consecutive weeks. Using a condom with these methods will help lower the risk of getting an STI.
