Regular vacation refers to menstruation. There is blood when you wipe with paper but it doesn’t flow out may be menstruation, or it may be abnormal uterine bleeding caused by vaginitis, polyps, endocrine disorders and so on. 1. Normal menstruation: If the bleeding coincides with the onset of menstruation, it may be menstruation. Due to the change of hormone levels in the body, the amount of menstruation will be relatively small in the first 1~2 days after the onset of menstruation because the endometrium has not been completely stripped off. 2. Abnormal uterine bleeding: (1) vaginitis: for vaginitis patients, due to the increase of local tissue inflammatory exudation, increased capillary permeability, so the patient will appear leucorrhoea, vulvar itching, a small amount of bleeding and other clinical manifestations. (2) polyps: for patients with endometrial polyps, cervical polyps, the main clinical manifestations of irregular vaginal bleeding. (3) Endocrine disorders: If the patient’s work pressure is relatively high, it will lead to endocrine disorders, which will affect the growth and development of follicles and their discharge, so the patient will have irregular vaginal bleeding. For women who have the symptom of wiping blood with paper but can’t flow out smoothly, if the symptom persists, it is recommended to go to the gynecology department of regular hospitals, improve ultrasound, sex hormone and other related examinations to clarify the cause of the disease and then actively treat under the guidance of doctors.
