Am I too small ?

Haley • Proud Soon-To-Be Teen Mommy . Blessed with a baby boy 💙
I am 23 weeks and pregnant with my first baby, he's a boy. Some days I feel bigger than others, maybe due to bloating. But I do notice that other woman as far along as me , being my friends, and woman in the glow community, are/were so much bigger than I am. The first two pictures were taken at times last week and the last one taken today. Someone plz give me some insightt on why I am so small. I weighed 139 pre pregnancy and 143/144 now.
