Excellent – I found this book incredibly helpful as it tells the reader absolutely everything you could want to know about pregnancy and has a special section on people trying to conceive and also for the next baby! Brilliant! The stages of pregnancy and how it goes by week to week and lets you know what to expect and also includes some of the more rare symptoms which is handy. I also like how it gives you approximate size and weight for the gestational age and how it is mainly written around answering questions about nearly everything you can think of! Nothing at all!
