Take the simple quiz below to test your knowledge of premenstrual syndrome.

  1. PMS is defined by symptoms that occur in the:
    • ovulation phase, the mid-point of the cycle, about day 14 in a 28-day cycle, when the egg is released
    • luteal phase -- the last 14 days of a cycle. During the luteal phase, progesterone levels peak and then decline, triggering disintegration of the endometrial wall -- the lining of the uterus -- and the beginning of menstruation.
    • follicular phase -- the first stage of the menstrual cycle, approximately day 1 to day 14
    • after menopause
