My Mother actually used this method trying to conceive a son. It did not work for her. I guess that is for the best, because if it had worked I wouldn't have been born. My husband and I charted for months and followed the plan for a boy. At my 15 week scan it appears that I will be having a girl. The one great thing about trying for a boy with Shettles, is he makes it very easy to get pregnant. Good luck everyone. wishing you all happy, healthy babies.
