I really liked The Pregnancy Book by Dr. and Mrs. Sears. She's an RN and has had 8 kids, so she really knows from experience. I thought it was the most honest book, and gave the most accurate depiction of what to expect from your body during each month. Obviously, I'm only in month 4 yet, but they have been spot on so far about most things. Most books really don't bother to try to tell the truth about 'real' morning sickness, and so on, and I feel like they just gloss over things and tell you to eat more crackers. This book wasn't a bit like that.
