Check out your local library first - they will have many of these titles also. Are you planning to join the ABA? I know it seems a bit early now, but your local group will have a library you can borrow from with lots of good pregnancy/birth and parenting books.

For pregnancy, I've found bb my best source of info. I think because everyone's experience is so different that no book is really going to cover it all. I read up the duff and found it amusing, but completely unhelpful.

For birth i found the materials I got for my Birthskills hypnobirthing course a really excellent source of info.

Hope the blood test is all good
