What are the symptoms of irregular menstruation?

The main symptoms of menstrual irregularity include: 1. Abnormal menstrual cycle: such as early menstruation (cycle shorter than 21 days), delayed menstruation (cycle delayed by more than 7 days, or even occurring every 40-50 days), and irregular menstrual cycle (varies by more than 7 days earlier or later for two consecutive cycles or more). 2. Abnormal menstrual flow:表现为 excessive menstrual bleeding (increased flow compared to previous cycles) or reduced menstrual flow (significantly decreased flow, with spotting). 3. Abnormal duration of menstruation: prolonged menstrual periods lasting more than 7 days, sometimes extending to half a month with continuous spotting. 4. Other symptoms: such as amenorrhea (absence of menstruation), prolonged menstrual bleeding, and uterine bleeding outside the menstrual period. These symptoms may be caused by various factors including hormonal imbalances, ovarian function decline, and endometrial disorders. Menstrual irregularities can affect women's health, and individuals experiencing these symptoms should seek timely medical evaluation and treatment.
