The key to understanding your fertility is what you feel at the vulva as you go about your normal daily activities.  You never have to touch the mucus, nor make any internal investigation.  This sensation is produced by the mucus as it leaves your body. If you feel dry it is because there is no mucus present.  By keeping a daily record (chart) of the sensation and appearance of mucus at the vulva you can learn to recognise the times of infertility, potential fertility and the time of ovulation.  Do not be concerned that your pattern does not conform to that of another woman.  Every woman is an individual with her own individual mucus pattern.  Most women quickly grasp the pattern of their fertility, and a trained tutor can ensure that you are correctly interpreting you chart.
