With the "What to expect" series there is one called "What to Eat When You're Expecting" - you might want to check that out and see. Also go to www.fitpregnancy.com there is a section on eating there as well. HTH
There is a book called the "12 Week Pregnancy" (I forgot the author!?!?), but it talks about getting your body ready before trying to concieve. It is a good book.
There is a wonderful book out there titled "Before Your Pregnancy: A 90 Day Guide for Couples on How to Prepare for a Healthy Conception"
by Lisa Mazzullo and Amy Ogle. I am sure that you could get it at your local book store or on Amazon.com.
Good luck!
