One of my players played through most of the her pregnancies, we had to hurry the last two games to avoid an early birth. Her second child was born also early, and we dropped the last session from the campaign, handling it through e-mail instead. I advise ending at least a month before the birth, and doing one-shots or card games.
Yeah, this seems like the way to go. If nothing else, I live on the top floor of a four-storey block of flats - it's bad enough climbing it normally, let alone when you're carrying a passenger!
My Wife Adds:
Remember to celebrate the fact of pregnancy with her instead of moving straight to how it effects the group. She says she got tired/frustrated with peoples reacting based on how it would affect them.
I can appreciate that. While one of the first things I thought of was how it might affect the game (pathetic, I know!) the group all made a big deal orf congratulating and talking about it during the session, and game-effect stuff only game up a few days later - like I said, we've all been chums outside of the game, and a few have shared flats & stuff with each other so they're all pretty good mates. But yeah, I guess I'll have to be careful how I phrase it - I don't want to sound judgemental, like I'm blaming her for not consulting me!

This reminds me: when the lady in question said she was pregnant, it was in the middle of a fight and about two or three hours into the session - it came quite out of the blue. That doesn't excuse the first thing anyoen said, after stunned silence, being what one of my players said: "Um... is that in or out of character?"
