First do not presume diagnosis since you have bleed per Vagina and Urethra
. There are multiple causes of bleeding per vagina and through the Urethra, urine mixed with blood. It is a feature of Urinary tract infection
to bleed. You had an infection of vagina called Bacterial Vaginosis
, the suppositories (foreign body) if left alone can cause bleed too. Yes the other cause at the age of 55 are Cancer. Since the doctor had done an internal examination it would not be a serious thing to worry. More over after the menopause
women tend to bleed because of dryness of vagina
. Do not panic. You see the Gynecologist once again and get the examination done once again to be rest assured.
