Causes of blood in vaginal discharge may involve several aspects: 1. Physiological factors: Women may experience slight bleeding in vaginal discharge around ovulation or just before or after menstruation due to hormonal fluctuations. This is a normal physiological phenomenon and does not require special treatment. 2. Gynecological inflammation: Conditions such as vaginitis or cervicitis, which may be caused by bacterial, fungal, or parasitic infections, can lead to increased vaginal discharge, abnormal odor, itching, and sometimes blood-tinged discharge. 3. Uterine disorders: Such as endometritis, cervical polyps, or endometrial polyps, which may cause menstrual irregularities, increased vaginal discharge, and bloody discharge.
