Just how I wanted to end my work week. One lady says "Doesn't she look so cute with her little bump?", other co-worker responds, "You better have them check again. Are you sure there aren't two in there? You're huge to be just starting out!"

I just smiled and said "I'm actually almost half-way done." Nice co-worker says, "Really?" And I say "Yes, I'll be 20 weeks next week." Rude co-worker just changes the subject.
