i have that what to expect when expecting but not really read it a lot but i do read week by week pregnancy book
I hate What to Expect.
I much prefer Your Pregnancy Week-By-Week (found at Walmart or Target for under $12). I also love The EVERYTHING Pregnancy Book.
For some fun reading: The Girlfriends' Guide to Pregnancy (outdated but makes it all the more hilarious when they talk about maternity fashion in the 90's).
There's so much more out there. I'd also recommend a really good breastfeeding book if you plan to nurse.
