People calling you fat when you're 6 months pregnant?!

I just can't believe the nerve some people have... I have a pretty small frame, and I didn't even start to show until recently, and basically everyone tells me I look small for 6 months... But today, I had some rude nurses from a different department tell me that it just looks like I'm gettin fat! I'm like, clearly, this is a baby bump. It upsets me that people think they are entitled to opinions when we're pregnant... There are just some things you DON'T say to a pregnant woman... Whether it be "you're too small" or "you look fat" so upset.
