If bleeding occurs in the course of white belt test, it is likely to be caused by contact bleeding caused by contact with the cervix when taking the white belt during the test. In addition, if there is local inflammation of the cervix, it may also lead to bleeding, so based on the results of the examination, we can initially understand the cause of bleeding. Another is that when there is inflammation of the vagina, the vaginal mucosal tissue will become congested and edematous, so clinically it may also lead to bleeding. In addition, the vaginal inflammation itself, such as trichomonas vaginalis, can cause a lot of bleeding spots on the vaginal mucosa, so it can cause bloody leucorrhea. Therefore, depending on the situation, different analyses will be given. After laboratory tests and gynecological examinations, we can basically make a preliminary diagnosis and then give the appropriate treatment.
