Anyone know of any moms-to-be competing in Beijing?

I can’t imagine there are any pregnant olympians who are actively competing

Yeah, I can’t think of a sport (MAYBE X-country skiing) they can safely do. (Leaving COVID out of it)

There's been a lot of pregnant olympians, although mostly in low contact events unless they didn't know yet. So usually like curling, shooting, although I remember one who was pretty far along and did one of the horseback events, can't remember her name though, or what event it was. But for the most part it's usually low contact, low impact events and with like 2 or 3 exceptions, only a few weeks along for most of them

I doubt it.  Although someone might find out during Drug testing.
