They saw how pale I was and new I was nascious so they all start saying uhoh you must be pregnant.
I hope you're feeling better. My coworkers (who all have children) used to say the same thing every time I felt even a cold coming on, even knowing that I don't want children. It didn't hurt my feelings or anything, but it was just really, really annoying.
You know how I got them to stop? Every single time they said they weren't feeling well I said, "Maybe you're pregnant!" I guess that after having a taste of their own medicine they realized how annoying it was.
