How many mm of amniotic fluid is normal at 14 weeks

Amniotic fluid at 14 weeks is usually in the normal range of 20-80mm.
Amniotic fluid is the fluid that fills the amniotic cavity and the environment in which the fetus grows in the uterus. Amniotic fluid serves to protect the fetus and cushion the fetus from irritation of the uterine wall. While the depth of amniotic fluid at 14 weeks is generally in the normal range of 20-80mm, if it is more than 80mm it is an increase in amniotic fluid, and less than 20mm it is a decrease in amniotic fluid, which is detrimental to the growth of the fetus.
The fetus lives in the uterus in the amniotic fluid, under normal circumstances, the amount of amniotic fluid in different gestational weeks between 300 ml to 2000 ml, the late pregnancy is about 800 ml to 1000 ml, less than 300 ml indicates that the amniotic fluid is too little, greater than 2000 ml indicates that the amniotic fluid is too much.
When you have too much or too little amniotic fluid in the 14th week of pregnancy, it is recommended to go to the hospital for examination and treatment in time to prevent serious consequences.
