hello and welcome, there are numerous methods but the method has to be tailored according to the comfort n tolerance of an individual. I would advise you to start with barrier contraception eg condoms and diaphragms, if you don t feel comfortable you can switch to oral contraceptive pills later, other methods are available but most people at your stage can cycle around these two methods comfortably, remember to keep a pregnancy kit with you in the event u are unsure, also keep PLAN B ie the morning after pill with u if u r worried about pregnancy. thanx
