Amber, google "fertility friend". This is the site that most of us use for our charts.

What you need to do is take your temp every morning before getting up, before even talking so you can get a resting temperature. Other than that you chart your other fertile signs - mucus, cervix position, OPK readings etc.

There are two good articles on the main BB page you can read about it -
Cervical Mucus, Ovulation & Your Fertility
Charting Your Cycle for Conception
