they hold their stomach to put attention on the fact that they are pregnant. the reason they do this is because they don't want people thinking they got big without being pregnant. probably a subconscious move too.
by holding their stomach, the pic goes from "hey look at that fat chick with the big belly" to "aww, look at the beautiful pregnant woman, she's glowing!

only answer that made a bit of sense, but i see skinny pregnant girls doing this where its evident they are pregnant and not fat.
