How long does it take for the stomach to get hard and tight at 38 weeks of pregnancy to go into labor? Under normal circumstances, most pregnant women in the middle and late stages of pregnancy will have physiological uterine contractions, the clinical manifestation of which is a feeling of tightness in the stomach, the duration of the symptom is short and the interval is long, and it is not accompanied by abdominal pain and will not lead to dilatation of the cervical opening, which is called false contraction. False contractions are not signs of labor and can be treated without special treatment until normal labor. If there is persistent tightness and hardness in the lower abdomen with regularity and shorter and shorter intervals, accompanied by abdominal pain, a small amount of vaginal bleeding, perineal discomfort and cervical dilatation, this is an aura of labor and the pregnant woman should be hospitalized in time for delivery. When your stomach is hard and tight at 38 weeks of pregnancy, don’t be overly nervous, you can observe the number of contractions, intervals and accompanying symptoms by yourself, and then go to the obstetrics department when clinical signs appear.
