38 weeks saw red but the stomach does not hurt, generally how long the birth time is not easy to determine, usually in 24-48 hours or so contractions start. 38 weeks belongs to the intrauterine full-term pregnancy, at any time there is the possibility of starting labor, the birth of the newborn is capable of survival.
In the 24-48 hours prior to the onset of labor, the fetal membranes near the endocervix separate from the uterine wall at that location and capillaries rupture, resulting in a small amount of bleeding, which mixes with the mucus of the cervical canal to form a light bloody mucus discharge, known as the erythrocyanosis, which is a relatively reliable sign that labor is about to begin.
If you see red at 38 weeks and your stomach doesn’t hurt, you can observe the situation at home, avoid stress, prepare the supplies needed by the pregnant woman and the newborn, pay attention to the changes of the fetal heartbeat and fetal movement, and if there are regular abdominal pains, water breakage, or an increase in the amount of vaginal bleeding, you need to go to the hospital with your family members to wait for the delivery.
