In general, the occurrence of pseudo contractions during pregnancy does not affect the fetus. Pregnant women have contractions before delivery, which are classified as pseudo contractions and true contractions depending on their nature. Pseudo contractions usually occur after 37 weeks of pregnancy, when the sensitivity of the uterine muscle layer is increased and easily perceived by the pregnant woman. Pseudo contractions are generally characterized by irregular contractions, long intervals, weakness, and duration shorter than 30 seconds and are not constant. The intensity of pseudo contractions does not increase, they usually appear at night and disappear in the morning, they are limited to the lower abdomen or inguinal region, they can cause slight distension and pain in the lower abdomen, they do not cause the opening of the cervix and the fetal head to drop, they can be suppressed by sedation, and therefore they do not affect the fetal development. Before delivery, pseudo contractions will become more and more frequent due to the fetal head descending and pulling to stimulate the lower part of the uterus, while excessive fatigue, mental tension, mood swings and stress will easily induce pseudo contractions. If you find that the contractions become more frequent and stronger, the interval between contractions becomes shorter and shorter, the lumbar pain is obviously aggravated, the lumbosacral area becomes sore, and the regular contractions accompanied by the opening of the uterus and the descending fetal head are true contractions, which are contractions of labor, and you need to go to the hospital for labor in time.
