Is it possible for a 17 year old to have menopause?

it is entirely possible. first you need to see your gyn and have them check your FSH, Estradiol, Estrogen and Testosterone levels (yes women also have testosterone) you could be going through peri-menopause which is when menopause starts entirely too early or you could have something i have which is PCOS (poly cystic ovarian syndrome). Please get checked out even if you don't believe what i am telling you.
