Symptoms of Irregular Menstruation

The main symptoms of irregular menstruation include the following aspects: 1. Abnormal menstrual cycle: such as early menstruation (menstrual cycle shorter than 21 days), delayed menstruation (menstrual cycle delayed by more than 7 days), or irregular menstrual cycle (cycle shorter than 21 days or longer than 35 days). 2. Abnormal duration of menstruation: prolonged menstruation (period lasting more than 7 days, even up to 2 weeks) or shortened menstruation (menstruation lasting only 1–2 days). 3. Abnormal menstrual flow: menorrhagia (excessive menstrual bleeding, possibly accompanied by anemia) or hypomenorrhea (very light bleeding, sometimes only spotting). 4. Other symptoms: such as prolonged menstrual bleeding, amenorrhea (absence of menstruation for more than 6 months), and dysmenorrhea (painful menstruation, which may be accompanied by headache, nausea, vomiting, and other symptoms). If the above symptoms occur, timely medical consultation is recommended to identify the cause and receive appropriate treatment.
