Those of you using NFP, how did you get started? I'm 6 month pp, and I haven't started ovulating yet, but we do not want to get pregnant again until my little one is at least a year but probably a bit older. We aren't interested in any artificial means, and my cycles are very irregular. It's looking like NFP is the way to go, but it's all a bit overwhelming. Does anyone know of any resources that talk about the specifics in detail? Any websites or books?
