Menstrual Cycle Length: The duration of one complete menstrual cycle from the first day of menstruation to the start of the next period. Cycles shorter than 21 days or longer than 35 days can indicate hormonal imbalances. Cycle Regularity: Regularity refers to how consistent the menstrual cycles are. Irregular cycles can be a sign of underlying health issues such as PCOS. Age of Menopause: The age at which a woman experiences her last menstrual period. Early menopause (before age 45) is associated with increased risks of osteoporosis and cardiovascular disease.
