Hi, and thanks for your medical question on eHealth forum!
No it is not normal to bleed after hysterectomy. Bleeding after hysterectomy could be due to infection of the stump, endometriosis, vaginosis, cervicitis (inflammation of the stump) or due to STD. It can also be due to hormonal imbalance of PCOD (if ovaries are left behind) or due to premenopause/menopause. Please consult your gynecologist regarding this.
Since a confirmed diagnosis cannot be given on net please consult your gynecologist regarding this. Hope this helps. Take care!
