How long does it take for your stomach to show if you are pregnant?

It usually takes about 12 to 16 weeks for a pregnant woman's stomach to begin to show. When the uterus begins to enlarge and put pressure on the abdominal muscles, the woman will start to experience a noticeable change in her waistline. This growth is typically gradual, with most women showing more clearly by 20 weeks. However, this timeline can vary from person to person depending on factors like the woman's body shape, the position of the baby, and the mother's weight before pregnancy.
