So many patients with abnormal vaginal bleeding (non-menstrual) often ask me online: What is the condition of the bleeding? What is the cause? I really can’t answer, sometimes I can only say I will help you guess: “Ovulatory bleeding? Cervical bleeding? Anal bleeding”? There are also pregnant patients who find bleeding and are very nervous that they are having a preterm miscarriage. Once a pregnant patient suddenly found there was blood in her panties, she was so nervous that she cried and came to the hospital. I told her that you need to do a gynecological examination to know your condition and that a gynecological examination will not cause you to miscarry, so she took my advice and after I did her gynecological examination I found that the leucorrhea in her vagina was milky white and the blood she found in her panties was not coming from her vagina at all. So I told her clearly that the blood found on your panties is definitely not related to gynecology, and if there is any more bleeding, pay attention to whether it is anal bleeding, so she went home in peace. She smiled and said, “No”. In other patients, abnormal vaginal bleeding may be caused by inflammation of the vagina or cervix, or it may be ovulatory bleeding. The bleeding from inflammation of the vagina or cervix does not come from the uterine cavity, so the treatment plan is completely different. You must need a doctor’s examination to clarify the site of the bleeding in order to find the cause of the bleeding and treat it properly. Many patients find abnormal bleeding and immediately go online to find the cause, applying the online symptoms to themselves, causing unnecessary thought of psychological burden.
