I have gotten more than a few comments that I'm barely showing/very small/etc. I'm at 19w and I'm 5'9'' so I attribute this to a combination of clothing choices, height, and that I'm not that far along. I just have heard this so much that it's messing with my psyche. Is there a bump size I should be? Doctor said everything was great last time I was there (go back next week), and everything else seems to be perfectly normal.
