If you experience a small amount of vaginal bleeding after intercourse, it is recommended to keep your vulva clean and not to blindly treat it with medication inserted into the vagina or to take medication to stop the bleeding. It is best to go to the hospital for a gynecological examination to find out if the bleeding is caused by damage to the vaginal mucosa or by contact bleeding due to vaginal or cervical abnormalities. Clinically, it is recommended to have a routine white belt test to rule out the possibility of vaginal inflammation. Screening for cervical cancer is also recommended, mainly to find out whether there is high-risk HPV infection in the cervix and whether there are cervical epithelial lesions, and then treatment will be given according to the results. During the bleeding period, it is not recommended to have sexual intercourse to avoid local infection.
