The uterus enlargement of pregnant women during pregnancy has certain regularity, which is manifested by the increase of fundus and abdominal circumference. The values of uterine height and abdominal circumference of pregnant women during pregnancy can infer the duration of pregnancy and the growth and development of the baby. Therefore, these two items must be done when pregnant women have a prenatal examination. Then, from 4 months to 5 months, how long is it normal to have a high abdominal circumference for one month? From 4 months to 5 months, how long is the uterine high abdominal circumference in one month? < P > Generally, it is measured once every 4 weeks from the 2th week of pregnancy, once every 2 weeks from the 28th week to the 35th week of pregnancy, and once a week after the 36th week of pregnancy. Let's take a look at the standards of palace height and abdominal circumference in various periods; Standard reference table for pregnant women's uterine height: 2 weeks of pregnancy: 16.-2.5CM; 21 weeks of pregnancy: 17.-21.5CM; 22 weeks of pregnancy: 18.-22.5CM; 23 weeks of pregnancy: 19.-23.5CM; 24 weeks of pregnancy: 2.-24.5CM; 25 weeks of pregnancy: 21.-25.5CM; 26 weeks of pregnancy: 21.5-26.5CM; 27 weeks of pregnancy: 22.5-27.5CM; 28 weeks of pregnancy: 23.-28.5CM; 29 weeks of pregnancy: 23.5-29.5CM; 3 weeks of pregnancy: 24.-3.5CM; 31 weeks of pregnancy: 25.-31.5CM; 32 weeks of pregnancy: 26.-32.5CM; 33 weeks of pregnancy: 27.-33.5CM; 34 weeks of pregnancy: 27.5-34.5CM; 35 weeks of pregnancy: 28.5-35.5CM; 36 weeks of pregnancy: 29.-36.5CM; 37 weeks of pregnancy: 29.5-37.5CM; 38 weeks of pregnancy: 3.5-38.5CM; 39 weeks of pregnancy: 31.-38.5CM; 4 weeks of pregnancy: 32.-38.5CM.

according to the pregnancy month, 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 uterus is about 2-3 fingers across the upper edge of pubic symphysis; At the end of the fourth month, the fundus reaches between the umbilicus and the upper edge of the pubic symphysis; At the end of the fifth month, 2 fingers below the umbilicus; At the end of the sixth month, the navel is flat; At the end of the seventh month, 3 fingers were pointed horizontally on the umbilicus; At the end of the eighth month, between the umbilicus and xiphoid process; At the end of the ninth month, the fundus is the highest, with 2 horizontal fingers under the xiphoid process; At the tenth month, the fetal head descends into the pelvis, and the fundus descends back to the level at the end of eight months.

there is another formula: (month× 3)+7 =-3 <; Gong Gao < 3 All are standard reference tables of abdominal circumference of normal pregnant women: the lower limit of abdominal circumference of pregnant women in May: 76; Upper limit of abdominal circumference: 89; Standard abdominal circumference: 82. What should I do if the uterine height is not long?

The uterine height refers to the length from the pubic symphysis of the lower abdomen to the bottom of the uterus, which is one of the data for judging the size of the uterus. The uterine height and abdominal circumference of pregnant women are closely related to the size of the fetus. In the first and second trimesters, there are certain standards for the monthly growth, usually 1cm for the height of uterus per week. At the later stage, the fetal weight can be estimated by measuring the height of uterus and abdominal circumference. Therefore, every time you do a prenatal examination, you should measure the height and abdominal circumference of the uterus to estimate the intrauterine development of the fetus. At the same time, we can also understand the intrauterine development of the fetus according to the curve of intrauterine pregnancy map, and judge whether it is stunted or macrosomia, so that it may be corrected by timely treatment.

The increase of uterine height indicates that the fetus is developing, and the position of uterine vault has changed, indicating that the fetus is developing normally. After pregnancy, the uterus will increase with the increase of the fetus, and the height of the uterus will increase, which is a normal phenomenon. Measure the height of the fundus and draw the measurement results on the pregnancy map to observe whether the fetal development is consistent with the gestational age.
