It's basically taking your waking temperature each morning and checking your cervical position and fluid each day. It's really fascinating, I think, to know when your body is gearing up to ovulate, and when you have ovulated. It was nice for me to know that I was for sure ovulating, as I'd been on the pill for about 11 years before DH and I decided to start trying. (My mom had ovarian cancer at a very young age...so I take the pill to help lower my risk.) I quit the pill and started charting about 4 or 5 months before we were ready to start trying. I'm also a planner and my husband and I are both extremely busy at work during the late spring, summer, and early fall, so we wanted to try to make sure the baby was born during the "off season."
A great book to get that explains it all is Taking Charge of Your Fertility. There is software included that's linked to a website to track everything on, but there's a fee associated with it. You can track everything on-line, too, with fertilityfriend.com. It's free!
If you have any questions once you get started, just let me know. :)
