38 weeks of pregnancy abdominal circumference standard

Pregnancy is a process that almost every woman must go through. The process of nurturing a new life is both wonderful and beautiful. Many pregnant mothers particularly enjoy the process of pregnancy. The physical health of pregnant mothers during pregnancy is the most noteworthy. As the months go by, the mother's waist circumference will also become larger. So what is the standard for waist circumference at 38 weeks of pregnancy? Let’s take a look together.

After the pregnant woman urinates, she lies flat on the bed and the distance from the midpoint of the upper edge of the pubic symphysis to the fundus of the uterus is measured with a soft tape measure. Generally, measurements should be taken every 4 weeks starting from the 20th week of pregnancy; every 2 weeks from the 28th to 35th week of pregnancy; and once a week after the 36th week of pregnancy. The measurement results are plotted on a pregnancy chart to see whether the fetal development is consistent with the gestational age.

In terms of gestational months, at the end of the first month, the uterus is slightly larger than before pregnancy, like a duck egg; at the end of the second month, it is as big as a fist; at the end of the third month, the fundus of the uterus is about 2 to 3 horizontal fingers above the upper edge of the pubic symphysis; at the end of the fourth month, the fundus of the uterus reaches between the navel and the upper edge of the pubic symphysis; at the end of the fifth month, it is 2 horizontal fingers below the navel; at the end of the sixth month, it is level with the navel; at the end of the seventh month, it is 3 horizontal fingers above the navel; at the end of the eighth month, it is between the navel and the xiphoid process; at the end of the ninth month, the fundus of the uterus is the highest, 2 horizontal fingers below the xiphoid process; at the end of the tenth month, the fetal head descends into the pelvis, and the fundus of the uterus descends back to the level at the end of the eighth month
