During pregnancy, the stomach grows slowly from bottom to top, and then slowly descends from top to bottom in the third trimester, which is such a constantly changing process.
The stomach usually gets bigger from 3 months.
When I was just pregnant, my uterus was still small and my stomach wouldn't be big. Outsiders can't tell I'm pregnant. But some mothers feel that their stomachs are hard, because they are a little soft and flat when lying flat.
After pregnancy, the stomach becomes hard, and it is no longer flat when lying flat, indicating that the uterus is getting bigger. I had this obvious feeling at the beginning of pregnancy, and I didn't know I was pregnant until my stomach became hard.
By the week of pregnancy 10, the uterus is as big as an orange. Pregnancy 12 weeks, as big as grapefruit, pregnancy 14 weeks, as small as watermelon. Around 0/2 weeks of pregnancy, many pregnant mothers begin to get bigger. Although outsiders can't see it, they will find that their stomachs are swollen.
By about 20 weeks of pregnancy, most pregnant mothers have exposed their bellies, and outsiders can easily see that they are pregnant. I was five months pregnant when I was pregnant with Bauer.
Where does the belly get bigger?
The belly is in the lower abdomen first and grows up slowly.
1. From the height of the palace, the belly has been getting bigger. The height of uterus refers to the height from pubic symphysis to the bottom of uterus.
At 12 weeks, the stomach was located near the pubic symphysis.
16 weeks, the stomach reached the middle of navel and pubic symphysis.
At 20 weeks, the belly reaches the position of 1 finger under the navel.
At 24 weeks, the abdomen reached 2 fingers above the navel.
At 28 weeks, the abdomen reaches 3 fingers above the navel.
At 32 weeks, the stomach reached the position between navel and xiphoid process.
At 36 weeks, the stomach reached the position of 2 fingers below xiphoid process.
At the 40th week, the stomach reached a position close to the xiphoid process.
From this development, we can clearly see that the stomach is growing upward.
About 32 weeks of pregnancy, the fetal head began to decline, and the protruding position of the stomach began to move down, from watermelon to grapefruit, that is, the original stomach was round, and later it would become an oval with a small top and a large bottom.
2. From the perspective of abdominal circumference, the abdominal circumference is significant after 20 weeks, especially the stomach.
At 20 weeks, the abdominal circumference standard was 82 cm, and at 40 weeks, the abdominal circumference standard was 94 cm, with little change. Because the shape of the stomach is changing, the abdominal circumference will repeat. In recent weeks, my abdominal circumference has sometimes even shrunk.
In short, the stomach began to get bigger from the lower abdomen, which was very obvious after 3 months and 5 months. Every pregnant mother's belly size is different, and the pregnancy is different in the morning and evening. This is because the size of the pregnant mother, the position of the fetus, the size of the fetus and the amount of amniotic fluid are different.
