OK, yes it's a third comment from me but I just realized I posted the same link that you already had. I meant to give you this one (http://www.americanpregnancy.org/preventingpregnancy/fertilityawarenessNFP.html). And another idea is to look into purchasing the book Taking Charge of Your Fertility. I haven't used it personally, but I know a lot of people have read it and it has really helped them learn more about their fertility and understand things well enough to effectively use FAM.
