The presence of blood in the leukorrhea before menstruation may be related to a small amount of endometrial shedding, cervical lesions and other diseases.
1. Small amount of endometrial shedding: at the beginning of menstruation, due to a small amount of endometrial shedding, the bleeding is low, resulting in the presence of blood in the leukorrhea, which is usually normal, and can be restored after the menstrual cycle is normal.
2. Cervical lesions: blood in the leukorrhea before menstruation may be related to the existence of uterine function abnormalities, such as cervical erosion, cervical polyps, cervical inflammation, etc., which will lead to leukorrhea abnormalities.
3. Other diseases: If there are endometriosis, pelvic inflammatory disease and other problems, it may cause a small amount of bleeding before menstruation, and in serious cases, it may also be accompanied by pain, so it is recommended to pay attention to it in time.
There may be other reasons for blood in the leukorrhea before menstruation, so it is recommended to go to the hospital for vaginal examination, ultrasound examination and routine examination of the leukorrhea, and give targeted treatment or therapy after the cause is clarified in the examination.
