Query: Great information

This book tells you things no other pregnancy book will tell you. Even though I didn't really follow it as a guide for pre-conception, I found myself going back to it for information during my pregnancy. It lets you know what herbs and medications are safe during pregnancy. The book also suggests good ideas for nutrition and over all health. It's worth the buy since most pregnancy books don't talk about specifics in medications and natural remedies.
