@Real Music,
Real Music, you just reminded me of someone I knew. It happened to be in a work situation.
I started to go through menopause maybe 3 years earlier than usual. I know my body pretty well, and mentioned during a related conversation that I hadn't had a period for 2 months, and doubted I ever would again (I didn't).
She was well aware of my child free status, and thought it was just the funniest thing to tell me that maybe I was pregnant. When I just kinda grunted at that, she really went at it, telling me that I might just be having a late pregnancy, wouldn't that be something, blah blah blah.
I said (she already knew this) that my husband had already had a vasectomy like 13 years before I even met him, so between my age, and the fact he had been sterilized, I really doubted it.
She said in this sing song voice "But those things can fail you know. hehehe" Like she really, really wanted me, in my mid 40's, with zero interest in children, with a husband 12 years older than me, also with no interest in kids, to have a baby.
At that point I figured that this BS had to end, so I just said "Well, if by some remote chance it is a pregnancy, I guess I'll be taking a day off soon to get an abortion."
Well, maybe that last part was a little funny.
