The U.S. Department of Argiculture has developed a individually tailored nutrition plan for pregnant and breast feeding women.

"MyPryramid Plan for Moms" includes an online tool that allows women to plug in their age,prepregnancy weight, due date, and amount of physical activity to find out the amount and types of food they should eat in each trimester.  A printable chart outlines recommended servings in each food group and includes tips on what foods to eat to meet those requirements.
