Hi, Of your menses are regular, there is no need of any medication. (ultrasound finding of PCOS & serum LH more than FSH: Does not require any treatment). Only thing you should remember is to eat healthy, exercise regularly & avoid putting on weight. It will help to reduce risk of diabetes for you. If your menses are irregular, you can take pills/progesterone to regularize it till marriage. Wish you good health.
