I think I speak for pregnant women everywhere when I say:
My uterus is not a matter of national security, a threat to public safety, out of compliance with OSHA regulations or in violation of any federal, state or local laws.
Therefore it is none of your damn business. If I want to have a cup of half regular/half decaf in the afternoon because I am tired and my boss scheduled me to be in a meeting from 3:30 - 5:00 PM, I am going to do so whether my nosy coworkers in the break room think it's OK for me or not.
Thank you in advance for butting out.
