After a woman is pregnant, as time passes, the fetus gets bigger and bigger and her abdomen gets bloated day by day, but the shape of the abdomen and the position of the fetus are not fixed in the body of each pregnant woman, and there are more or less some differences. The upper part of the fetus is positioned up close to the stomach, which is manifested by a significant bulge in the upper abdomen. In contrast to the upper pregnancy, the position of the fetus is relatively lower, which is reflected by the obvious bulge in the lower abdomen. It is generally believed that pregnant women with upper pregnancy will eat less and feel hungry soon during pregnancy, while pregnant women with lower pregnancy will not have this symptom, these two types of pregnancy belly have different formation reasons, to distinguish the sex of the fetus by this symptom does not exist any scientific basis. But whether you are pregnant or not, you must pay attention to a balanced diet and moderate exercise during pregnancy to maintain a happy mood, which is conducive to the health of the pregnant woman and the growth and development of the fetus.
