Weight gain

Has anyone had someone else comment on their weight? Every time I have had an appointment lately and I call my mom afterwards, she asks me how much weight I've gained. I started at 116 and am now 133 at my appointment today at 28 weeks so 17 pounds total. Doctor says I am right on track as well as everyone else saying I look all belly and not like I've gained much. But my mom acts like I am getting huge or gaining too fast or something!  It just irks me I guess. I am not sure what to say to her besides the doctor says I am on target. We get along fine but GEEZ! Lol has this happened to anyone else??
