1, some pregnant women have a particularly good appetite during pregnancy, so they gain weight faster. The belly is also very big, probably 40 to 50 kilograms heavier than before pregnancy. That pregnant woman's navel will definitely stick out.
2, pregnant women's navel is prominent, sometimes because of the child's position. If the baby's back is turned to the mother, the pregnant woman's stomach will bulge forward, and then the whole stomach will stretch forward to push out the pregnant mother's navel. Therefore, even many thin pregnant mothers will have their navel protruding.
3, another reason will stand out, that is, when some pregnant mothers were born, the doctor cut his umbilical cord, which was too long.
Usually, if you pay attention to observation, you will find that some people have deep navel, and some people's navel itself is a bit prominent. A woman with a protruding navel will have a slightly bigger belly after pregnancy, and the navel will be pushed out regardless of the baby's position.
