The vast majority of women cannot feel fetal movement around 12 weeks of pregnancy, although small movements of fetal limbs can occur at the end of 12 weeks of pregnancy, but self-conscious fetal movement is not obvious. Of course, due to the influence of individual differences, it is normal for a few pregnant women to infect the fetus with a slight sense of fluctuation at 12 weeks. Most women will have conscious fetal movement in 16-18 weeks of pregnancy, which feels similar to bubbles coming out of the hand or fish spitting bubbles, and may be easily ignored if not felt carefully, usually more active at night and in the afternoon. At the end of the 20th week of pregnancy, the fetal movement may increase significantly by 10-30%. Usually, at the end of 28 weeks of pregnancy, the fetus moves freely, and most of the fetuses form a certain activity and sleep rhythm, so it is recommended that pregnant women start counting fetal movements at this time. If after 28 weeks of pregnancy, the fetal movement count is less than 10 times in 2 hours or decreased by 50%, it indicates the possibility of fetal hypoxia. Therefore, if there is a significant decrease or increase in fetal movement, further electronic fetal heart monitoring and obstetric ultrasound should be performed. If the fetus is hypoxic, prompt obstetric management is required. In addition, if a pregnant woman has not felt fetal movement for more than 5 months, she should go to the hospital for ultrasound examination to see if the fetus is developing normally.
