If a woman is having blood down there with mucus during a non-menstrual period, consider having abnormal vaginal bleeding. If it happens to be during ovulation and there is no intercourse stimulation, it is a manifestation of ovulatory bleeding caused by a small amount of endometrial flaking due to the fluctuating drop of estrogen during ovulation. However, if a woman has blood and mucus down there after intercourse, it is caused by a localized lesion in the cervix, such as common cervical polyps, or even cervical erosion or cervical intraepithelial neoplasia. However, if a woman is pregnant and there is blood and mucus down there, it is due to a preterm miscarriage or even an ectopic pregnancy.
