In the 5th month of pregnancy, the belly should be slightly protruding and bulging. However, due to personal height and fetal position, some pregnant women have anterior uterus position and some have posterior uterus position. Anterior uterus position will have more protruding belly after pregnancy, while if it is posterior uterus position, it will not show particularly pregnant after pregnancy, which are normal performance. During this period, as long as the ultrasound is done to check the development of the fetus, if the fetus is developing normally, it is not necessary to worry too much. If there is no abnormality in the fetal examination, there is no need for special treatment. If the fetus is too small or small for the ultrasound, you need to enhance nutrition by eating more milk, lean meat, egg yolk and other nutrient-rich foods to enhance nutrition.
