hi I m a 17 year old girl, only 4 11 and I don t know my weight but I m rather thin, and i ve only menstruated when i was 14 which is two years ago and only once and then again when i was 16 and only twice for two months, and ever since, my voice and body figure still looks like a little girls, though i have long legs and a short torso, I m way far from my peers, what should i do or take?
