I'm in love with the Mayo Clinic Guide to a Healthy Pregnancy. I've had it through all of my pregnancies. It shows you even what the fetus looks like week by week and how it changes, how big it is, what develops at what week, symptoms throughout each week, how to prepare for labor/delivery and even had a miscarriage section which I thought was very useful especially when I had my mmc in July of 2015. It discusses the pros/cons of epidurals, spinal blocks, c-sections and naturally delivery (even has detailed pictures on dilation) so I highly recommend it! Talks about diets, what medications are ok, which are not and just about answers every question I had.
