I learned NFP from books and successfully avoided PG for 2.5 years and I just found out (after 4 mos of trying) that I successfully achieved PG using the same method (all from books).<br><br>
Here's what you need:<br>
-2 books: NFP and <i>Taking Charge of your Fertility</i> by Toni Weischler<br>
The NFP book is very dry and reads like a text book, but has wonderful information, so the TCOYF book is a good place to start because it adds humor and reads much more fluidly.<br><br>
-A BBT (basal body thermometer), BD is supposed to be the best brand and can be ordered online or gotten from a drug store<br><br>
I charted my cycles on a paper chart, but ovusoft has computer software that you can use to chart too. One place that is great for questions once you start charting is ovusoft.com. There is a large chat forum for questions about avoiding, charting, TTC and everything else inbetween. Most of the women on those boards use the ovusoft software, so you can get answers for that too.<br><br>
I hope this helps.
Couple to Couple League sells the NFP book (by Kippley), the thermometer, and charts and more info in a "home study course" (see <a href="http://www.ccli.org" target="_blank">www.ccli.org</a> for details.) The "course" part is nice because you can send in your first three charts for an expert to review and give you feedback on. You can call/write for help whenever you need it the first year. This can give you a lot of peace of mind. It's not only important how easy and cost effective the method is, but also how well you will learn NFP! <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile"><br>
We used the home study course and have successfully avoided for 2 years and counting.<br>
Also, I would second the use of the paper charts, especially when you are first learning. I think it's much easier to learn what is going on. As far as books go, TCOYF is a great book, especially to get the general idea, but I think the NFP book gives a lot better advice on TTA. Like the previous poster said, read both!<br><br>
NFP isn't quite the same as FAM, and I think that FAM is far more accurate. We have used it and been very happy. And I think it was fine to learn from a book, though I did have a sort of mentor which may have made a difference.
I'm pretty sure NFP is the same as FAM, except with NFP you abstain during your fertile window, while with FAM you can either abstain or use condoms. If there are other differences, then I don't know about them.
