What are observable changes from a pregnant person?

Observable changes in a pregnant person can include physical alterations such as a growing abdomen, breast enlargement, and darkening of the areolas. Hormonal shifts may lead to skin changes, such as the "pregnancy glow" or the appearance of stretch marks. Additionally, some individuals may experience changes in posture or gait as their body adapts to accommodate the growing fetus. Emotional changes, while not always visible, can also be significant during this time.
