Just need to rant!

Has anyone else had people constantly commenting on their bump or lack thereof? I have had sooo many people saying that I look too skinny or too tiny. I had one person ask me today when I was gonna start looking pregnant. I am 21 weeks with my first, I haven't gained any weight yet and I am about 5 ft tall 175 lbs give or take a few. I carry most of my weight in my bust and belly, with some loose skin left from a fair amount of weight loss last year. All of these people are friends that I admire and respect, it just really bothers me that people just automatically feel it is their duty or right to comment on a woman's figure if they know she is pregnant.
