Honestly, I would read all the books on vegan pregnancy I could get my hands on. There are only a few out there, anyway, so it wouldn't be too tough to read them all. Here are the books I can find:
Vegan Pregnancy Survival Guide by Sayward Rebhal
Skinny Bitch Bun in the Oven by Rory Freedman and Kim Barnouin
The Everything Vegan Pregnancy Book by Dr. Reed Mangels
Pregnancy, Children, and the Vegan Diet by Dr. Michael Klaper
A number of other vegan health books have a section on pregnancy, too. For example: Vegan For Life by Jack Norris and Virginia Messina.
