Ok I'm seeing all these pics of mommas with big bellies and Im 12 weeks and not showing at all. I know everyone's body is different, but the fetus to baby to infant growth process is still the same, right? Me not showing makes sense to me since the baby is as big as a clementine. What would make a belly stick out so big when the baby is so small? Help me understand. If I go by my book, I shouldn't be showing, right?
