hi, im 17 years old. when i started my periods i only had them every 4 months. then when i because sexually active consistently i got them every month on time, now my periods are late every month and the only time i get them is if i have sex. im really confused, when i went to my gynecologist she said just too lose weight and then come back but i dont think thats the problem. i have hair on my chest and chin that grows really fast and is visible if i dont shave every day. im only 17 this shouldnt be happening to me. if anyone has any advice i would really appreciate it.View Thread
