###Human: Having bleeding along with urination after sex. What causes it? ###Assistant: Hi. If there is bleeding in urine, then consult a doctor soon and test her urine. If there is blood, do not take it lightly and it may require sonography and other tests to find out the cause. If it is bleeding from a private part and if it is not related to urination, then give time for healing and do not have sex for at least four to six weeks. If the bleeding is not stopped, then consult a nearby gynecologist to see the source of infection clinically. If she has bled every time after having sex, then consult a nearby gynecologist and check for a cervical lesion clinically.
