Anyone ever tried the Jonas method -lunar fertility?

It is kind of freaking me out. I decided to have another look at the calendar - anyway my chem preg last month, i believe I fell pregnant during the time the lunar calendar indicated i would be most fertile that cycle (this is because I seem to have ovulated a week sooner than I thought I would) - anyway that is a chem preg

I had another look at the calendar for the next few months, but it only indicates April, May and June with a gender, the next months after all the way to 2014 there is no gender indicated. what does this mean?? does anyone know why there is no gender prediction from July onwards?
