Generally at the end of the 12th week of pregnancy, the fetus’s limbs have been able to move, at this time the pregnant woman herself will not feel fetal movement. Usually pregnant women can feel fetal movement around 16-20 weeks of pregnancy. 1, mid-pregnancy: around 16-20 weeks can feel fetal movement is relatively slight, if not. Slowly the fetal movement will become more and more energetic and regular; 2, late in pregnancy: 24-28 weeks is the more active stage of fetal movement, the fetus in the uterus can feel the outside world stimulation. And in 28 weeks began to appear sleep and wake cycle, doctors recommend from 28 weeks to count the fetal movement every day, as a way to monitor the baby’s health. Under normal circumstances fetal movement is no less than 3-5 times an hour, and the number of distinct fetal movements in 12 hours is 30-40 or more. Fetal movement after full term may slow down a little in the last two weeks of pregnancy, which is normal. Normal fetal movement indicates that the placenta is functioning well and the fetus is growing and developing soundly in the uterus. However, if a pregnant woman feels a significant decrease in fetal movement, she should immediately go to the hospital and contact her doctor for further fetal testing to avoid placental precocity, fetal hypoxia, and other conditions.
