The time it takes for a pregnant woman's tummy to start showing varies from person to person. On average, most women begin to show between 12 and 16 weeks of pregnancy. However, factors such as body type, muscle tone, and whether it's your first pregnancy can influence when your baby bump becomes noticeable. Additionally, if you are carrying multiples or have had previous pregnancies, you may show earlier. It's important to remember that every woman's body is unique and there is no right or wrong time for your tummy to start showing. Embrace the changes happening in your body and enjoy this exciting journey!
