Hysterectomy is the surgical removal of the uterus. It's normal to have bloody vaginal discharge for several days to several weeks after a hysterectomy, as the sutures dissolve and the tissue heals. So you'll likely need to wear sanitary pads during that time.
Generally, vaginal bleeding after hysterectomy should be light. You may notice occasional spotting or a pink discharge. If bleeding after hysterectomy is as heavy as a menstrual period or lasts longer than six weeks, consult your doctor for an evaluation.
