The presence of blood in the leukorrhea at full-term pregnancy may be a sign of impending labor. The appearance of blood in the leukorrhea in full-term pregnancy may be commonly known as redness, which usually appears in the 24-48 hours before labor is initiated, due to the separation of the fetal membranes near the endocervical opening from the uterine wall at that place, and a small amount of bleeding due to the rupture of capillaries, which is a reliable sign of impending labor. If the vaginal bleeding is heavy and reaches or exceeds the amount of menstruation, it is necessary to consider whether it is placenta praevia or placental abruption. There will be some precursors before labor starts, such as irregular contractions, the feeling of the fetus descending, redness, etc. You should be prepared for labor when these symptoms occur. If there are regular contractions, disappearance of the cervical canal, dilatation of the mouth of the uterus, and the descent of the fetal prelude, it means that labor is imminent. Pregnant women with symptoms of labor need to go to the hospital in time and wait for delivery.
