If fresh blood flows after intercourse and it is not painful or itchy, it must be paid great attention. The most common cause is contact bleeding caused by early cervical cancer. It is recommended to go to the hospital for examination as soon as possible. First of all, screening for cervical cancer should be done, and through gynecological examination, it is also possible to understand whether there are superfluous organisms locally in the cervix, and also where the bleeding point actually is. If there are superfluous organisms in the cervix, such as cervical polyps, they can also cause contact bleeding. It is recommended to have surgery as soon as possible, usually 3-7 days after menstruation, and send the removed polyps to pathology for examination.
