Both menstruating mothers and primiparous mothers find it difficult to notice fetal movement at 14 weeks of pregnancy, and usually feel fetal movement after 4 months. The fetal movement is the activity of the fetus in the uterine cavity. As the fetus grows and develops in the uterine cavity, when the nerves and muscles reach a certain level of development, the fetus can move its limbs. Since the fetus is still relatively small at 14 weeks of pregnancy and the amniotic fluid is relatively large, pregnant women usually do not feel the fetal movement. Usually around 4-5 months of pregnancy, pregnant women can feel the fetal movement by themselves. In addition, the perception of fetal movement is also affected by whether the placenta is in the anterior wall of the uterus, the thickness of the pregnant woman’s abdominal fat and the difference in self-perception. At 14 weeks of pregnancy, we have entered the middle stage of pregnancy, which is relatively stable, but the fetal development needs more nutrition than before, so we suggest pregnant women pay attention to the nutrition and diversity of diet after entering the middle stage of pregnancy, and appropriately supplement calcium, iron and other trace elements.
