Hi there,
It needs to be determined if the bleeding is from vagina or
urinary tract. If there is blood in the urine the possible causes are
urinary tract infection, kidney stones, bladder infection, bladder stones etc.Bleeding from the vagina after sex should be taken seriously.PIDs,STIs,atrophic vaginitis,cervical or endometrial polyps, cervical erosions are few common causes of bleeding after sex.
