When bleeding occurs during intercourse after menstruation, the first thing to do is to take oral anti-inflammatory drugs for two days, the main purpose of which is to prevent infection. Because the menstruation has just cleared, at this time the tiny blood vessels will still be oozing blood, and the new endometrium also starts to grow and there is no epithelial covering on the surface yet, so it will cause bleeding after intercourse. It is also important to exclude bleeding from intercourse caused by vaginal injury, then injury to the vaginal mucosa can cause bleeding from intercourse. Inflammatory diseases of the reproductive tract such as chronic cervicitis, vaginitis, endometritis and other inflammatory diseases of the genitals can also cause bleeding during intercourse. In addition, bleeding during intercourse is one of the danger signs of cervical cancer, so it is recommended to go to the hospital for detailed examination after cleanliness.
