“Redness in pregnancy is a reliable sign that labor is about to begin. During the first 24-48 hours of labor, the cervical opening begins to dilate, causing the fetal membranes near the cervical opening to separate from the uterine wall there, and the capillaries rupture, resulting in a small amount of vaginal bleeding that mixes with the mucus in the cervical canal and is discharged. Generally speaking, the labor pains will start within 24 hours after the redness and the labor phase will begin. However, there are many pregnant women who go into labor a few days or even a week after the onset of redness.
