Circle and the abdomen begins to change rapidly from the second trimester of pregnancy. However, the first signs of a growing baby become noticeable from 4-10 weeks (individually for each woman). A visit to the gynecologist is a paramount task facing any woman who learned about her pregnancy.
The abdominal circle during pregnancy is not evenly changing, but jumps like. Up to 12-14 weeks, the tummy is almost imperceptible, and strangers can only guess. During this period of pregnancy, the sizes can be compared with a large orange. And she has not yet affected the circumference of the abdomen. But the more the term of pregnancy, the faster the uterus will increase in size.
Starting from 15 weeks, your gynecologist will regularly measure the circumference of the abdomen and the height of the morning of the uterus. Analyzing this data in the dynamics, you can notice violations of the growth rate of the fetus and other factors.
One of them is the calculation of the approximate body mass of the fetus. To do this, the standing height of the uterus is multiplied by a pregnant woman's abdomen. The resulting digit is the approximate mass of the fetus in grams. Gynecologists argue that the error of this method is 150-200 grams.
And moms at the same time call a much greater error, up to a kilogram. This difference can be caused by additional factors affecting the abdomen's circumference during pregnancy (a circle to pregnancy, a tendency to completeness and much more).
Also, the dynamics of changes in the abdomen of the abdomen for weeks of pregnancy can allow the doctor in time to identify anything or a multi-way basis, as well as take appropriate measures. The logic here is simple, and even at home you can independently do the appropriate measurements.
The future kid grows, gaining weight from the first week of its development, but at the beginning of pregnancy this increase is very small, and therefore it does not affect the size of the abdomen. For example, in the third week of pregnancy, the diameter of the fertilized egg is 2-4 mm, on the eighth - 22 mm.
Ten weeks after conception, its growth is already about seven centimeters, and the weight of about 25 g. Another month, the growth of the embryo will increase twice, and the weight is four times. Thanks to the rapid growth of the future child at the end of the first trimester of pregnancy, the uterus, increasing in size, begins to perform a little from the Lonnoye. At this time, the woman notes that the indicators of the abdomen circle gradually increase.
At the 20th week of development, the fruit weighs about 300 grams, and another month - 700-800 grams. The most active future kid grows in the third trimester. So, at the 28th week of pregnancy, it grows up to 30-35 cm and weigh no less than 1000 grams, and at 36 weeks - 46-48 cm and at least 2300
A little later, the growth of the belly will slow down, as the fruit will not be so actively developing. It should be remembered that there is no direct dependence between the abdomen of the abdomen during pregnancy and the weight of the future, because the size of the abdomen also depends on the number of accumulating waters and the size of the uterus.
