Why isn't my belly big during pregnancy?

A small baby bump during pregnancy may be caused by various factors, some of which are normal and others potentially concerning. If the pregnancy is still in early stages, the pregnant woman's belly may not appear large, which is normal because in the early weeks the fetus is only a few millimeters in size and abdominal changes may not be obvious. Women with lower body weight may also have less noticeable bumps. A pregnant woman's physical condition can also influence the size of her belly. If the belly is not growing as expected, it could indicate poor fetal development, possibly due to genetic or congenital abnormalities, or insufficient nutrient supply to the fetus. If a pregnant woman notices that her belly is not growing adequately, she should seek medical attention promptly to identify and address any potential issues.
