How should I read the ultrasound report of pregnancy

The ultrasound report of pregnancy is mainly to see if there is a gestational sac, if there is a fetal bud, if there is a primitive heart tube pulsation and the size of the fetal head and hip diameter, as well as the development of the fetus, in addition to the amount of amniotic fluid, the position of the placenta and the function of the placenta, etc. In the early stages, a gestational sac should be seen in the uterus at about 40 days of menopause, with a yolk sac inside. If it is around seven weeks, the primitive heart tube should be seen pulsating. If it is eight weeks, the head-rump diameter should be about 2 cm. If it is late in pregnancy, it is important to know the exact position of the placenta and the function of the placenta. If the placental function has reached grade III it means that the placenta has aging and the fetus may have hypoxia in utero, which should be treated clinically. If the amniotic fluid volume decreases, for example, the amniotic fluid index is less than 8 cm, then the diagnosis of low amniotic fluid is made at this time. It is also recommended to give clinical management and to exclude the possibility of fetal kidney malformation.
