If a woman has yellowish leucorrhea and blood during her non-menstrual period, it is often necessary to consider abnormal leucorrhea caused by cervical erosion and abnormal vaginal bleeding. Under normal circumstances, a woman’s leukorrhea is colorless or white, but when there is yellowish leukorrhea and blood inside the leukorrhea, the first thing to consider is the presence of cervical erosion, which causes abnormal leukorrhea secretions, which is a manifestation of cervicitis. At the same time, because the local congestion of celiac disease is obvious, so after the stimulation of intercourse or gynecological internal examination, it may cause a significant blood discharge from the surface of the cervix, which is also called contact bleeding. However, if a woman has yellow leucorrhea with blood during ovulation, in addition to the abnormal leucorrhea caused by cervicitis, she should also consider the ovulatory bleeding caused by a small amount of endothelial peeling due to the fluctuation of estrogen during ovulation, and for women with cervical polyps, or cervical intraepithelial neoplasia, or even cervical cancer, it will often cause yellow leucorrhea with blood. This may take longer and there will be continuous vaginal discharge. The woman who has yellowish blood in her leukorrhea needs to go to the hospital for gynecological examination of ultrasound and internal TCT; HPV to confirm the specific cause of the leukorrhea and then treat it symptomatically.
