Redness accompanied by mild abdominal pain, usually 24-48 hours before labor starts, how long it takes to give birth varies from person to person, and needs to be combined with the contractions, the fetus and the pelvis and other conditions to make a comprehensive judgment. In the late stages of pregnancy, if there are symptoms such as redness and irregular abdominal pain, it is considered to be labor with premonitory signs. The redness usually occurs 24-48 hours before the start of labor, which means that the fetal membranes near the endocervix are separated from the uterine wall at that place, and the capillaries rupture and bleed in small amounts, which mixes with mucus in the cervical canal and is excreted in a light blood, which is a more reliable sign of the imminent start of labor. Most labor starts within 1-2 days after seeing red with mild abdominal pain, while the exact time of labor varies from person to person, depending on the combination of contractions, pelvis and size of the fetus. If you experience redness accompanied by mild abdominal pain, you should go to the hospital promptly for examination and treatment under the guidance of your doctor.
