Hi Lisa1, i haven't got that book but got another e-book called path to pregnancy. What a load of rubbish, i actually got my money back! I really would be careful about buying anything like that off the internet. All the testimonials make them sound so convincing.
I have since gone to the library (much cheaper), there is a book by Emma Cannon called The baby making bible which is like the one you are talking about. It is written by a fertility specalist with tips for both natuaral and ivf conceptions. It links chinese and western practices in terms of finding whats right for you in helping to get pregnant etc.
Haven't finished reading it all yet so can't make too much comment but certainly some interesting things for me to start thinking about. At least its cost me nothing if it isn't any help.
Hope that helps you a little on whether to buy Lisa Olsens one. xx
