Stomach drop

When your stomach drops does it look smaller??

It looks like my stomach look smaller and it worries me I told my mom and she says no but yesterday I went to the store and the cashier ask me how far along I was I told her and she said wow you look small.

Two weeks ago i went to the dr and they said baby weight was 6lb 1oz and last week I went again and they said it was 6lb.. worried she isn't growing or something anybody else had similar problem?
