Menstrual irregularities refer to any deviations from the normal menstrual cycle. A typical menstrual cycle ranges from 21 to 35 days, and bleeding lasts about 2 to 7 days. Irregularities can include changes in frequency, duration, or amount of bleeding. Common types include oligomenorrhea (infrequent periods), menorrhagia (heavy bleeding), amenorrhea (absence of periods), and dysmenorrhea (painful periods).
