What causes you to miss your period two months in a row?

Answer 1

Pregnancy or lactation may cause periods to cease.

Another reason may be serious malnutrition. Female athletes or those who do a great deal of exercise, such as bullimics, may experience amenorrhea (ceasing of menstruation). Various hormonal disturbances, and even tumors may cause this disorder. Finally, menopause will cause menstrual cycles to taper off and finally cease. This is normal in middle aged women.
