If there is vaginal bleeding after intercourse, the first thing to rule out is the following. The first, more common, is cervicitis. Cervicitis and cervical erosion, especially severe cervical erosion, can cause a little vaginal bleeding after intercourse. The second type, cervical polyps. The most common are cervical polyps, which can also cause vaginal bleeding when stimulated by intercourse. The third type is precancerous lesions of the cervix or cervical cancer. The earliest clinical manifestation of cervical cancer is vaginal bleeding after coitus. If it is cervicitis, or to rule out cervical cancer, we should go to the hospital to do cervical cancer screening, including cytology, virology testing, to rule out cervical cancer or cervical precancerous lesions. If the bleeding is caused by cervical polyps, cervical polyp removal should be performed 3-7 days after menstruation. Once the condition is treated, there will be no vaginal bleeding after intercourse.
