hi, i was just wondering...i havent had my menstrual for about 2-3 months now. im not on any birth control or depo shot. i do get cramps when its close to the date I m supposed to get my period but nothing. I m only 22 and i dont know whats wrong. maybe because of my weight? because im 5 7 @ 270lbs. anything abnormal? also, when i was about 16-17 a doctor said to me that i had a cyst rupture in my overies. will i ever have a chance to start my own family one day? please get back to me asap, anxiously awaiting your reply.
