Around the expected date of labor, before the official delivery, there are usually some symptoms that indicate that the pregnant woman will soon go into labor, i.e., aura of labor; such as false labor (irregular abdominal pains, often at night, disappearing in the morning), the feeling of the fetus descending (also known as the feeling of relief), the red (small amount of bleeding from the vagina with no obvious cause, pink or dark brown). Redness is due to the peeling off of the fetal membranes from the uterine wall near the opening of the cervix and the rupture of capillaries with a small amount of bleeding and mixing with the mucus plug in the cervical canal, which is eliminated vaginally; it is a relatively reliable sign that labor is about to begin, and most pregnant women go into labor within 24-48 hours of the sighting of redness, with a few extending the period to a week. The interval between the onset of labor is usually longer in primigravida than in primigravida. For primigravid women, it is often encountered in clinical practice that labor is not imminent for several days after seeing red, as long as the fetal movement is normal, the fetal heart response is good (fetal heart rate monitoring suggests that the NST response type), and the amount of vaginal red is not much (have ruled out the placenta previa, placenta previa, and other pathologies), we should listen to the doctor’s advice, and wait patiently.
