When a woman is pregnant, her body undergoes great changes. In addition to hormonal changes in the body, the navel will also protrude, usually in the seventh month of pregnancy, although the exact time varies from person to person. Because each pregnant woman’s own situation is different, there is no absolute answer as to when the navel will bulge out. Some women may show it very clearly at around seven months, but there are some pregnant mothers who do not experience this phenomenon throughout their pregnancy. In fact, regardless of whether it is protruding or not, it is a normal pregnancy phenomenon and mothers need not worry and bother about it. In addition, mothers-to-be who have a more pronounced belly button are generally thinner, and if the fetus in the belly is developing quickly and well, then the belly button will protrude more obviously. If you encounter this situation, mothers should not worry too much, until after the birth, it will recover on its own as before. However, if the pregnant mother’s navel is congenitally stunted, an umbilical hernia may appear during pregnancy, and this must be taken seriously. In summary, whether the pregnant woman’s belly button will bulge out or not will need to be decided according to the mother-to-be’s own situation, and during this period, the pregnant woman must do her own personal care to keep her umbilicus warm.
