Symptoms of endometrial shedding are mainly characterized by vaginal bleeding and mild pain in the abdomen. Generally speaking, endometrial shedding is clinically manifested as a woman’s menstrual period, because the endometrium will be subjected to the combined effect of estrogen and progesterone, and will have cyclical shedding. The shedding of the endometrium is accompanied by the blood in the uterine cavity, which is mixed and discharged from the body, manifesting as vaginal bleeding. At the same time, the uterus is also affected by hormone levels, resulting in mild pain caused by contractions. During a woman’s menstrual period, she may also experience frequent urination, breast tenderness, and lumbosacral pain, all of which are normal physiological phenomena. If there is abnormal vaginal bleeding, or if there is any abnormality in menstruation, it is recommended that you seek medical attention for symptomatic treatment.
