Does amniotic fluid decrease in the late stages of pregnancy?

Patient's question:

No

Doctor's answer:

Hello, Amniotic Fluid Index. During ultrasound, with the pregnant woman's umbilicus as the center, it is divided into 4 regions: upper, lower, left, and right. The sum of the amniotic fluid depths in these 4 regions gives the Amniotic Fluid Index. The normal value of the Amniotic Fluid Index in the late stage of pregnancy is 8.
