Decreased fetal movement at 33 weeks of pregnancy is not normal. If you feel that the fetal movement is reduced, you should first consider the possibility of intrauterine distress, and it is recommended to visit the hospital in time to make a clear diagnosis. The number of fetal movements will increase with the number of months of pregnancy after 28 weeks of pregnancy. After pregnancy, pregnant women can check the fetal movement at home by themselves, once in the morning, once in the middle and once in the evening, and take the average value of the fetal movement. If the number of fetal movements at 33 weeks of pregnancy is about 50% less than before, it may be due to various causes of fetal hypoxia in utero, such as low amniotic fluid and cord winding. It is recommended to go to the obstetrics and gynecology department for fetal heartbeat and pregnancy ultrasound examination to understand the specific situation of the fetus in the uterus and take symptomatic treatment, such as oxygen absorption, position adjustment, etc. If necessary, fluid infusion is needed to correct the fetal intrauterine hypoxia. Pregnant women must keep a happy mood during pregnancy, because too much emotion is not only bad for their health, but also may affect the development of the fetus.
