Primiparas may assume that the belly “inflates” evenly from the navel, but this is not the case. The stomach does not immediately take the shape of a ball, as in recent months. The first and second trimesters are characterized by a flattened shape elongated upward, from the pubis to the solar plexus. The bulge expands and rises, gradually sticking out more and more. Clear rounded shapes are formed by the 7th month.
Where does the belly begin to grow during pregnancy: from bottom to top. It gradually “creeps” towards the solar plexus, increasing in volume.
With twins, the growth rate and shape differ from the norms of pregnancy with one child. First of all, it depends on the location of the babies. If they lie in the sequence belly-baby-baby-back, then the belly protrudes forward more. If the crumbs are located on the sides, it spreads out in breadth.
When carrying one child, the shape will also change as the baby moves inside. But these changes are noticeable in the later stages. The larger the fruit becomes, the more noticeable the change in shape will be. Don’t be alarmed if your mother goes to bed in the evening with a wide oval and wakes up in the morning with a ball sticking out forward.
Abdominal growth during pregnancy by week:
• by the 12th week, the fundus of the uterus reaches the line of the symphysis pubis (nothing is visible);
• by the 16th, the bottom is located between the navel and pubis (the bulge begins to be visible);
• at 24 weeks it reaches the navel (the belly is clearly noticeable, but not yet round);
• on the 32nd, the fundus is located between the navel and the xiphoid process (the shape becomes spherical);
• at 36 weeks the uterus reaches the xiphoid process (lower border of the ribs);
• after 36, the uterus gradually descends, moving the fetus “towards the exit”.
Pregnancy among specialists is calculated by weeks, since it is in weekly periods that the stages of fetal development are contained.
To calculate at what month of pregnancy the belly begins to grow, you need to divide the number of weeks by 4.
There are 4 full weeks in a month - hence the numbers. This information may be needed to explain the situation to a husband who is poorly versed in the intricacies, but months are 100% clear to him.
It is difficult to calculate growth during pregnancy by month, because the data will not be accurate enough.
