If you have vaginal bleeding after intercourse, there is no need to be nervous. If the vaginal bleeding is caused by a hymenal fracture from the first sexual intercourse, it is recommended to keep the vulva clean and to change the sanitary napkin regularly, mainly to avoid local infection. If the vaginal bleeding is not due to the first sexual intercourse, but to intercourse after having already had sexual intercourse, then it is considered to be vaginal inflammation, cervical inflammation, cervical precancer or cervical polyps. Cervical cancer may also cause bleeding during intercourse. Therefore, it is necessary to have a detailed examination, such as a routine white blood test and a screening test for cervical cancer, and clinical treatment will be given according to the results.
