Some of the advantages of using the calendar methods in family planning is that you do not have to see a doctor in order to implement this method, and you do not have to remember to take a pill or get a shot. The main disadvantage to this method is the fact that many women do not always have a regular cycle. Even those who normally do, may have times when the do not, this would make the calendar method unreliable.
That question is far too broad to be answered adequately here. Family planning is ideal for someone who is careful enough to pay close attention to their bodies cues and does not want to use hormones or Birth Control. It's also important that you only have one partner using natural family planning as there is no way to protect against STD's. I recommend the book "Taking Charge of Your Fertility" by Toni Weschler because it gives open minded, factual information about all the different types of ways to chart your fertility and the pros and cons of each.
When considering family planning, a couple may decide to start a family or to refrain from starting a family. They may also consider if they want to use contraception methods or not.
