“You’re really putting on the weight now!”

This is what a coworker said to me recently. I’m 22 weeks. I try to eat healthy and I work out 5 times a week. I’m busting my ass to manage the weight gain and at my 20 week appointment I’d gained 10 lbs. I seriously wanted to cry. I know you can’t take this crap seriously but why are people so insensitive toward pregnant women?
