Concave-convex changes in the navel during pregnancy are common physiological phenomena in pregnant women. These changes are related to many factors, but have nothing to do with the gender of the fetus. The following are some of the main factors that affect the convexity of pregnant women's navel.

1.& nbsp; Individual physical differences

Loose and tight skin: If a pregnant woman has loose abdominal skin or has more abdominal fat, the navel will more likely bulge outward as the fetus grows. In contrast, pregnant women with tight abdominal skin have a belly

The umbilicus may remain concave or flat.

2.& nbsp; Fetal development and activity

Fetal size and activity: Rapid fetal development and varying levels of activity can also affect the status of the navel. Larger fetuses or fetuses with frequent fetal movements are more likely to make pregnant women's navel bulge.

Placenta location: The location of the placenta will also affect the unevenness of the navel. If the placenta is located on the anterior wall of the uterus, the pressure on the abdomen is greater, which may cause the navel to bulge; while when the placenta is located on the posterior wall of the uterus,

There is less pressure on the abdomen, and the navel may remain concave or flat.

3.& nbsp; Living habits of pregnant women

Exercise habits: Women who exercise regularly have tight abdominal muscles and better skin elasticity, which can better withstand the pressure brought by fetal growth, so their navel may remain concave or flat.

Rest and fatigue: If a pregnant woman is too tired, her navel may bulge due to changes in fetal position.

4.& nbsp; Cleaning and care of navel

Cleaning principles: Pregnant women should keep their navel clean and follow the principle of "three prohibitions and one cleaning", that is, squeezing, oppression, and digging are prohibited, and keep it clean.

The uneven changes in the navel of a pregnant woman are mainly determined by factors such as personal constitution, fetal development and activities, and the pregnant woman's living habits, and have nothing to do with the gender of the fetus. Pregnant women should pay attention to their health

In case of illness, maintain good living habits and follow correct navel care principles to ensure health during pregnancy.
