Redness in late pregnancy accompanied by abdominal pain usually means that the pregnant woman is about to enter into labor, and the specific time of labor varies due to the individual condition of the pregnant woman. The total duration of labor usually does not exceed 24 hours for primiparous women and 17 hours for women in labor. The redness of a pregnant woman refers to the separation of the fetal membranes near the inner cervical opening from the uterine wall, resulting in a small amount of bleeding due to the rupture of capillaries and the discharge of blood mixed with mucus in the cervical canal in the form of light bloody mucus, which is a reliable sign that labor is about to start. Redness accompanied by abdominal pain indicates that the pregnant woman has regular and gradually increasing contractions, each contraction usually lasts more than 30 seconds with an interval of 5-6 minutes, which is an important sign of labor. Therefore, pregnant women who experience redness accompanied by abdominal pain should be admitted to the hospital in time for delivery. If there is more vaginal bleeding and the amount of blood reaches or even exceeds the amount of menstruation, it is necessary to check for prenatal bleeding disorders, such as placenta praevia or placental abruption, which may cause postpartum hemorrhage, puerperal infection and poor prognosis of the perinatal baby. Pregnant women should undergo timely examination and treatment, correct anemia, continuously monitor the intrauterine condition of the fetus, and if necessary, follow the doctor’s advice to terminate the pregnancy in time.
