Fetal movement in the lower abdomen at 28 weeks of pregnancy is generally normal, and this condition is directly related to the fetal position of the fetus. Most of the fetal movements start to appear around 20 weeks of pregnancy, 28 weeks of pregnancy is the active period of fetal movements, because of the high frequency of fetal activities, so the fetal position at 28 weeks of pregnancy is not yet fixed, fetal movements may occur in different positions in the lower abdomen, generally the fetal movements generated by the fetal limb parts touching the uterine wall are more easily felt. When the fetus is in the head position, the limbs are often located above the umbilicus, and the fetal movements in the upper abdomen are more likely to be felt, so regular prenatal checkups are sufficient. When the fetus is in breech, sitting or transverse position, the limbs are in the lower abdomen and the movement in the lower abdomen will be more frequent.
