Never Expanding Belly

So every week I have my coworker take a pic of me to send to my mom. Looking through the past few weeks, it does not look like I'm getting bigger at all. In fact, the only part of me getting larger is my chest, which was already large to begin with. Maybe the babies have decided to head north to live up there.

I know I'll eventually get large, but I now think it's going to be a Violet Beauregard kind of growth - instantly huge and round...
