The size of your belly during pregnancy can vary depending on various factors, including the position of the baby, your body type, and muscle tone. While some people believe that carrying a boy results in a smaller belly, there is no scientific evidence to support this claim. The growth of your belly primarily depends on how your body accommodates and carries the baby, rather than the gender of the child. It's important to remember that every pregnancy is unique and individual experiences may differ. If you have concerns about your pregnancy or any specific symptoms, it's always best to consult with your healthcare provider for personalized advice and guidance.
