Fewer fetal movements in 28 weeks of pregnancy may be normal and related to the baby’s poor movement and the low sensitivity of the pregnant woman. However, if it is a sudden decrease in fetal movement in recent days, it may not be normal, and it is recommended to seek timely medical attention.1. Normal: If the fetal movement has been very small since the beginning of the pregnancy, it may be that the fetus itself is relatively quiet and does not move well; in addition, if the amplitude of the fetal movement is small, and the sensitivity of the pregnant woman is relatively low, it may be that the fetus is moving, but the pregnant woman does not feel it, and therefore mistakenly believe that the fetal movement is small. Suggest close observation, regular ultrasound examination, 28 weeks pregnant for fetal heart monitoring is still early, but, if the medical advice for fetal heart monitoring, can also be checked, ultrasound as well as fetal monitoring are no abnormality of close observation, regular checkups can be; 2, abnormal: fetal movement is generally 16-20 weeks of pregnancy, and gradually enhance, increase, gestation 28-32 weeks of the fetal movement is the most frequent, and then gradually reduce, reduce. Therefore, 28 weeks of pregnancy fetal movement should be more, stronger, if the previous fetal movement has been normal, in recent days, suddenly reduced, weakened, may be the fetus intrauterine hypoxia, belong to the abnormal situation. It is recommended that the pregnant woman should have an ultrasound examination in time, and if necessary, fetal heart monitoring, to check whether the fetus is suffering from hypoxia, which can be treated with oxygen in the left lateral recumbent position. If the condition of fetal hypoxia is more serious and has affected its normal development, terminate the pregnancy if necessary.
