Can you have a small bump but big baby?
In the same way that every woman's body is different, every baby bump is different. The size of your pregnancy bump does not necessarily mean your baby is too large or too small or that your baby is not healthy and well. Baby bumps come in all different shapes and sizes.
What determines belly shape?
The real factors behind your belly shape are: Your muscular structure—including the elasticity of your abdominal wall. Whether or not recti diastasis occurs. The fetal position of the growing baby.
Can you not be showing at 6 months pregnant?
Yes, most likely. There isn't a specific time when moms-to-be are supposed to start showing, because it happens differently for different women. As long as your healthcare provider says your baby is developing properly and your weight gain is on track, there's no cause for concern.
