When a woman sees redness at 38 weeks of pregnancy, but her belly does not hurt, she can usually continue to observe the situation, and at the same time, she can move properly, and she needs to pay attention to counting the fetal movements. When redness appears at 38 weeks of pregnancy, it is usually due to a small amount of vaginal bleeding caused by the rupture of capillaries due to the detachment of the fetal membranes from the wall of the uterus, which is called preterm labor. Generally, about 24 to 48 hours after the onset of redness, regular uterine contractions may occur and lead to the official onset of labor. Therefore, when there is no official onset of labor, there is no need to carry out any treatment, but to observe the specific situation of contractions, when the stomach does not hurt, it means that there is no obvious uterine contractions, so there is no need to rush to the hospital obstetrics department for delivery. Usually when labor officially starts, there will be regular uterine contractions, so the woman will have abdominal pain once every 5 to 6 minutes, and the pain can last for more than 30 seconds, and then she can go to the hospital obstetrics department for delivery. Since the redness and the absence of pain in the belly does not mean that labor is not official, so you just need to observe and pay attention to counting the fetal movements.
