Height of the bottom of the uterus - for weeks and months

The height of the bottom of the uterus by weeks is the most important indicator, which is able to say a lot about the development of pregnancy.

Based on this indicator, you can determine when an egg and sperm met, that is, when conception took place. If the size of the uterus and the height of its bottom (the bottom is called the upper part of the organ) do not correspond to the term, it can talk about various pathologies, for example, the delay in the development of the fetus.

For example, if this indicator increases slowly, the doctor can come to the conclusion that in this case there is a placental insufficiency. If the uterus grows rapidly, it can talk about multiple pregnancies or the development of polyhydramnios.

Per week by centimeter

The height of the bottom of the uterus by weeks is determined by the gynecologist at each reception. When pregnancy is not so noticeable, the doctor examines your abdomen with your fingers, then applies a measuring tape measure or a flexible centimeter tape to measure it . You can say that every week the uterus grows by about one centimeter. And if in four weeks of pregnancy the size of this important organ does not exceed a large egg, then by forty weeks it reaches the volumes of a very large watermelon.

With the onset of three months of an interesting position, the uterus bottom looks out from behind the pubic bone - its growth is about 14 cm. At week 19, it reaches a size of 16 to 24 cm. By the middle of the period (20 weeks), the height of the uterus bottom is calculated by weeks With the support of the gestation period, that is, the number of weeks is equal to the growth of the uterus in cm. Simply put, at the 22nd week this parameter is 22 cm, on 23rd week - already 23.

Above the navel

There will come a time when you yourself can easily determine what became the height of the bottom of the uterus. 30 weeks is the time when you will do it without problems. By this time, by the way, its height is from 29 to 31 cm, if we take as an initial level pubic symphysis. If the umbilical cavity is taken as the reference point, the uterus rises about 5 cm above the navel.

Please note that the physique and individual characteristics of a woman have a serious impact on this indicator, therefore, in two pregnant women at the same time, it can be very different. When the middle of pregnancy passes, the organ almost at all reaches the level of the navel - by this time about 26 cm is the height of the bottom of the uterus. 28 weeks - the time when this occurs, or the uterus by this time exceeds the level of the navel by two centimeters.

37 weeks: the uterus no longer grows

The height of the uterine fundus by weeks is a parameter that changes up to the 37th week of pregnancy. After this period comes, the stomach is, as a rule, not growing. By this time, the bottom of the uterus reaches the chest, towering above the pubis by 36-40 cm.

If you expect twins, then this maximum reaches the stomach much earlier, and then begins to grow actively in breadth. Near the end of the pregnancy, he can even go down a few centimeters, because your baby is preparing for birth, pressing his head to the pelvic floor - this is how one of the precursors of childbirth manifests.
