Taking your temp every morning at the same time without leaving bed and recording it is the basic form of charting. When you ovulate your temp spikes (very slightly). This helps you to know when you are ovulating, but the more complex forms of charting help better with TTC. You can also check cervix position, openness, and firmness and cervical mucous to tell you a few days before hand that you are about to ovulate. This is when you either have sex of avoid sex depending on what you are trying to do (prevent or get pregnant). Do a google search on natural family planning or fertility awareness method for more details. There are also many free online places to enter this information instead of doing it with paper and pencil.
