In the late pregnancy, ultrasound examinations often report that fine dots of light floating in the amniotic fluid are mostly fetal fat, hair shedding and fetal feces on the surface of the fetus’ body. 1. The fetal heart monitoring should be done to closely follow the fetal heart condition. If fetal heart monitoring shows intrauterine distress, the pregnancy should be terminated promptly and a cesarean section should be performed if necessary. The presence of fine dots of light floating in the amniotic fluid does not clearly indicate the presence of disease, so pregnant women should not worry too much. At this time, it is generally recommended to have regular maternity checkups to closely observe the changes in amniotic fluid and the growth and development of the fetus. You need to pay attention to rest, maintain a good state of mind, and develop good habits of life and diet, which is conducive to the healthy growth of the fetus and the health of the pregnant woman.
