Menstruation is the regular occurrence of menstrual periods in females about every 4 weeks. Start of menstruation is called Menarche. Failure to menstruate is called “Delayed Menarche” or “Primary Amenorrhea”. Absence of periods is Amenorrhea (Secondary Amenorrhea when periods occurred, and then disappeared). Cessation of menstruation is Menopause, which is preceded by a time called Perimenopause. Menstrual symptoms include menstrual pain, absent periods (amenorrhea), irregular periods, abnormal vaginal bleeding, and many other symptoms. Menstruation-related disorders include Pre-Menstrual Syndrome, Pre-Menstrual Dysphoric Disorder (PMDD), Anovulation, Fertility Disorders, Female Infertility, and many others.
