Amenorrhea: There are probably a dozen reasons young women miss a period. Are you not talking to your mom or your girlfriends. If you are not pregnant then don't drive yourself crazy worrying about pregnancy. Stress, dieting, too much exercise, and just the simple fact that once in awhile you do not ovulate. There are a dozen common reasons for missing a period. You are not pregnant.
