There are many reasons for faint vaginal bleeding after intercourse. Consider that it is caused by men’s rough movements that lead to breakage of the tiny mucosal vessels in the vagina and cervix. Pay attention to vaginal hygiene and do not have any sexual intercourse for a week in the near future. If the bleeding is particularly heavy, you should go to the hospital as soon as possible to stop the bleeding. If there is chronic cervicitis and cervical erosion, it will lead to bleeding after intercourse. Consider that it is caused by contact bleeding. It is recommended to do cervical TCT and HPV examination, if there is any problem, further colposcopy is needed to exclude cervical diseases, if it is determined that there is cervical disease, physical treatment or cervical conization surgery is needed. If there are endometrial polyps or cervical canal polyps, they will cause bleeding after intercourse and need to be surgically removed. If you are in ovulation, they will cause ovulatory bleeding and need to be regulated with progesterone.
