I was on the pill for a number of years and didn't care for it. One of my biggest complaints in that it killed my libido. We've been using Natural Family Planning for about 12 years now - it involves monthly charting of one's cycle using one's waking temperature, cervical mucus observations, and even the position of the cervix. "Taking Charge of Your Fertility" is definitely worth reading.
We've used it consistently (and exclusively) to both achieve and avoid pregnancy. My husband and I have two children, each conceived on the first try. We've also successfully avoided pregnancy for the remainder of that 12 year time period.
Feel free to email me if you'd like more info.
