The baby making bible

Jenna
So I'm ttc ( naturally ) and thought I'd buy this book called "The Baby Making Bible" 
I started reading it this afternoon and although a lot of it makes sense in what you should and shouldn't do, I find some of it way to much to take in! 
I felt quiet relaxed about ttc before reading this book, but now I feel stressed out about all the things I could be doing wrong and all the random things it's telling me to avoid! 
Has anyone else felt this way with a " baby book" 
Is it best just to put the book away and don't over-think it all??
