Amenorrhea has both natural and unnatural causes, according to the Mayo Clinic. Excessive exercising can cause up to 25 percent of female athletes to stop having a period, states WebMD. Some dancers also have this issue. Eating disorders such as bulimia can lead to a temporary halt in ovulation. Getting pregnant or starting menopause are two natural conditions that cause a woman's period to stop completely.
