What is the reason for leukorrhea with blood?

Patient's question:

Asexuality, blood appearing in vaginal discharge one week after menstruation and in large amounts

Doctor's answer:

Bleeding in leukorrhea can be of physiological or pathological origin. Generally, some women may experience ovulatory bleeding during their ovulation period, also known as mid-cycle bleeding, which refers to light bleeding between two normal menstrual cycles. It may be accompanied by varying degrees of mild abdominal pain. If the symptoms are mild, no treatment is needed. However, if the bleeding is heavy or affects fertility, medication can be used.
However, bloody leukorrhea should also be considered as a possible symptom of the following conditions: cervical polyps, acute vaginitis, severe cervical erosion, and others. Additionally, sometimes due to the insertion of an intrauterine device (IUD), small blood streaks may also be present in the leukorrhea.
