During pregnancy, every woman's body is unique, and the timing of when your tummy starts showing a bump can vary. On average, most women begin to show a noticeable baby bump between 12-16 weeks. However, if you had a larger stomach before pregnancy, it may take longer for your bump to become prominent. Factors such as your body type, muscle tone, and the position of the baby can also influence when your tummy becomes hard and starts showing. It's important to remember that each pregnancy is different, so don't worry if your bump doesn't appear at the same time as others. If you have concerns about the growth or development of your baby or any other pregnancy-related issues, it's always best to consult with your healthcare provider for personalized advice and guidance.
