Amenorrhea means the lack of menstrual bleeding. Amenorrhea (not having a period) is normal during pregnancy, but if the person is not pregnant or breastfeeding and did not go through menopause yet, it can be a symptom that something could be wrong. Primary amenorrhea occurs when a girl did not get her first period by the age of 16. Secondary amenorrhea means that there was an absence of at least 3 menstrual periods.
