The fact that you want to poop all the time at 37 weeks of pregnancy is generally not a sign of labor or preterm labor, so it’s not necessarily a sign that you’re going to have a baby. As the fetus develops, the uterus continues to grow, and at 37 weeks the uterine fundus can reach 2 transverse fingers below the xiphoid process, which may cause pressure and irritation to the rectum, resulting in the urge to poop all the time, or pressure on the bladder, resulting in an increase in the frequency of urination, which is generally not a sign that labor is imminent or premonitory labor is imminent. Symptoms that occur before the onset of labor, i.e., premonitory labor, include irregular contractions (i.e., contractions of varying frequency, irregularity, and intensity without gradual increase in intensity, not accompanied by disappearance of the cervical canal, dilatation of the mouth of the uterus, etc.), the sensation of descent of the fetus (due to the descent of the prenatally exposed fetus, the pregnant woman consciously feels that the stomach is falling, and her epigastric area feels comfortable compared to the previous period), and the sighting of red. The most important signs of labor onset are regular and gradually increasing contractions (i.e. each contraction lasts 30 seconds or more, with an interval of 5-6 minutes between contractions), as well as progressive loss of the cervical canal, dilatation of the uterine orifice, and the descent of the prenatal nipple. To determine whether labor is imminent, consult a medical professional.
