I am almost 21 years old and have not had a period in two years. I started menses at age 16, had a normal cycle for 1 year, bleed almost non-stop (became anemic) for a year, had normal cycles for about a year after being put Loestrin bc pills then they stopped altogether. I am in good health now, have 20% body fat (which my health teacher said is good), excercise 4-6 days a week and have no family history of fertility problems. Was bulimic for 2 years, but have been at a healthy weight for a year now and still no period. I get a lot of hot flashes and find myself crying for no reason more and more frequently. Also, my breasts feel sore all the time and I have awful migranes. People assume I am pregnant or going through menopause, but I have not been sexually active since Feb. 2010 and I am only 21! Please, any advice would be welcome
