Don't worry about when you're ovulating. IF the moon has anything to do with gender swaying, it's probably by slight, natural, fluctuations in fertility that are easily overcome with other methods. (As in, who cares what the moon is doing to you when you can completely dry up your CM by using antihistamines, KWIM??)
You can try your rock salt lamp and see if it works. Just use any light you have and leave it on all night long for three days at O time. See if it helps to reset your cycle at 28 days. If not, no great loss, you can still sway anyway, but it sure seems worth a try.
