Have any you been insulted for being pregnant?

I'm at motherhood shopping for shirts for work. This lady maybe around my mother age.
Asked how far along I was. I said between 5-6 months. Then she point to her daughter who 6- 7months ( skinny and smaller than me) try to compare to me to her. 
Then she asked if I was carry twins. I said no. She look shocked because I was bigger not further along.
😔😕😨😢 wow this kind  this stuff doesn't get to me but right now it is.  I'm in tears in a dressing room.
 
I plus size normal 14-16 size, I haven't gain weight and been very good at maintaining my weight.
Am I  that big?  I'm carrying a boy. I know women carry different.
I think it my emotions... I don't cry but this was hurtful even for a first time mom that loved her body.
What have been your experience?
