Vaginal bleeding after intercourse is called contact bleeding, which is abnormal and may be caused by chronic cervicitis, cervical polyp, or cervical precancer or cervical cancer. If it is caused by cervical inflammation, local treatment of cervical inflammation should be carried out; if it is caused by cervical polyp, it should be removed surgically; if it is caused by cervical precancer, cervical pre-cancer screening should be done and the next treatment should be determined according to the results of the examination. You can also do cervical biopsy directly, if you see obvious lesions on the cervix, and determine the next treatment according to the pathological results of the biopsy.
