Since you're a racer you might get a kick out of this. It's a little anecdotal story about the first pregnant woman I ever skied with. Since I saw her (and her kids) this past winter, I think it's a fun story. I'm not going to give her name but it probably wouldn't be hard for you to figure out.
About ten years ago, I was on the tram dock at Jackson Hole and a friend introduced me to a married couple who were friends of his. My friend had been a World Cup downhiller on the US Ski Team, and his friends were ski racing buddies. The wife was a former US Team downhiller also and she was five months (or more?) pregnant with her first child. We all rode up the tram together and I remember thinking we would probably be "taking it easy" as we skied down.
Well, her definition of taking it easy was pretty interesting. The conditions were soft-chopped powder and crud and all I recall is trying to keep her in sight as she flew down the mountain. It was one of the fastest trips down the Hobacks I've ever taken. When we rode back up the tram, I asked her about skiing and pregnancy. She told me that her doctor said she could ski within her bounds. She said she actually felt like the change in her center of gravity caused by the baby made her ski better.
Anyway, she skied while pregnant with both her kids with no ill effects. I skied with the whole family for a couple of runs this past season and the kids, as you might expect, are absolute rippers.
Best of luck to you and the baby and have fun at Hood!
