The 39th week of pregnancy is a full-term pregnancy, and labor may occur at any time. There are usually symptoms of preterm labor, including redness, abdominal cramping and frequent urination. Several symptoms may appear at the same time, or separately, or none of them may appear, and the labor may occur directly with regular contractions. The absence of redness in the abdomen is a normal phenomenon. Because redness is the bleeding caused by the rupture of small blood vessels at the edge of the fetal membrane, not everyone will experience redness. The pain in the abdomen at this time may be a false contraction, or it may indicate that the woman is about to give birth. Firstly, if the pain is not severe and there is no vaginal bleeding, the pain is short and irregular, the intervals are long and irregular, and there is no increase in the intensity of contractions, it may be a pseudo contraction and can be closely observed without treatment. Secondly, the pregnant woman is 39 weeks pregnant, belongs to the late pregnancy, the fetus has been developed, if at this time there is a small abdominal pain, accompanied by regular contractions, the degree of contractions continue to increase, may indicate that the approaching labor, need to go to the hospital in time for delivery. Finally, it is recommended that pregnant women should pay attention to keeping warm during pregnancy, avoid getting cold, take more rest, avoid straining, keep a relaxed mood and get enough sleep. In case of abdominal cramping and regular contractions, hospitalization is recommended for observation and preparation for delivery.
