It is completely normal for your tummy to still feel soft at 24 weeks pregnant. The firmness of your belly depends on various factors such as the position of the baby, the amount of amniotic fluid, and your body type. As your pregnancy progresses, your uterus will continue to expand and your belly will gradually become firmer. However, every woman's experience is different, so if you have any concerns or unusual symptoms, it's always best to consult with your healthcare provider for reassurance and guidance.
