I never read the Girlfriend's guide, but I know a lot of my friends liked it. I had a book called Your Pregnancy Week by Week by Glade Curtis. I had the What to Expect book with my first child, but like many of the rest of you, it made me crazy. The whole diet thing was just insane, imho.

As for exercising, my doctor was pretty cool with me doing whatever I had been doing previous to getting pg. Just be careful, use your common sense and listen to your body. I went to a triathlon that my husband was doing the bike portion of when I was about 33 weeks along with #4 and I walked about the whole day. Felt fine the whole day so I thought I would be fine. Ended up with nasty, nasty sciatica that kept me basically on my back for a week and a half and continued to recur for the remainder of my pregnancy. Everyone always says your baby is well insulated from knocks and all that, and it's very true. However, it's no fun being pregnant injured. So be careful of you!
