At 14 weeks, the fetus has activity, but it is difficult for the pregnant woman to perceive it. Generally, around 18-20 weeks of pregnancy, the pregnant woman can be conscious of fetal movement. Fetal movement refers to fetal somatic activity. At 6 weeks of gestation, embryonic buds and primitive heart tube pulsations can be seen. At 14 weeks of gestation, there is faint intrauterine fetal activity, but the pregnant woman is not yet able to feel it, and fetal activity can usually be seen by ultrasonography. Fetal movement increases gradually as the pregnancy progresses, and it usually takes about 18-20 weeks of gestation for a pregnant woman to recognize fetal movement. It usually reaches its peak at 32-34 weeks of gestation and gradually decreases after 38 weeks of gestation. In the middle and late stages of pregnancy, pregnant women can monitor fetal movement to understand the condition of the fetus initially, if there is an abnormally frequent or reduced fetal movement, should consult a doctor in time.
