A slight tingling pain in the stomach and sometimes a hardening of the stomach in the late pregnancy are symptoms caused by contractions of the uterus, pseudo contractions. Pseudocontractions are usually not regular, the pain is not too long, and the pain is not particularly intense. If you feel the pain is more obvious, you can gently touch your belly to improve the symptoms. During this period try to pay attention to relax, do not be too nervous, usually pay attention not to overwork, should pay attention to observe the fetal heartbeat and fetal movement changes. Under normal circumstances, the fetal heart rate should be kept between 120 and 160 beats per minute. If it is lower than this value or exceeds it, it is a sign of intrauterine ischemia and hypoxia of the fetus, and oxygen should be administered in time to avoid intrauterine distress of the fetus.
