Never ask if she is a virgin.
Definitely don't ask how old she is or how much she weighs..
Are you Crazy?
How pregnant are you?
Happened to a pregnant friend of mine recently. She was in the Dr.'s office waiting on her appointment. Saw another woman waiting as well, assumed the woman was pregnant too...nope...she didn't know what to say after that.
Say different things and find out. lol
