The term “great aunt” generally refers to a woman’s menstrual period. During menstruation, women may experience breast tenderness, bloating or pain in the lower abdomen, fatigue, mood swings and other symptoms, but there are individual differences. 1. Breast swelling and pain: Due to the large changes in estrogen and progesterone levels during menstruation, women may experience breast swelling and pain during menstruation. 2. Swelling or pain in the lower abdomen: Because of pelvic congestion during menstruation and the effect of prostaglandins, women may experience swelling and pain in the lower abdomen. 3. Fatigue and weakness: As women have greater energy consumption and weaker resistance during menstruation, they may experience fatigue and generalized weakness. 4. Mood swings: Because hormone levels in the body change during menstruation, some women may experience greater mood swings, such as irritability, anxiety, irritability and other emotional manifestations. Some women may not experience any significant discomfort during menstruation, and there are large individual differences. If you experience significant discomfort during menstruation, it is recommended that you go to the hospital in time for treatment.
