A New Approach to Charting and Learning

billingsMentor avoids the use of stamps and symbols by visualising fertility as a simple bar chart that combines fertility with the rules of the Billings Method. This is an important aspect of the e-learning experience.

billingsMentor Version 2 offers a new data entry form and additional guidance for entering your fertility symptoms.

You have the option of learning the Billings Method independently by using the automated guidance of the web service, or with a fertility educator.

billingsMentor is of great help to any woman who wants to learn about her fertility while avoiding the use of contraceptive drugs or devices.

Fertility Awareness

billingsMentor helps you to follow the Billings Method by:

  • guiding you in making a proper entry of your fertility symptoms;
  • automatically generating your fertility chart;
  • interpreting your symptoms and your fertility status on each day;
  • recognizing your Peak day in a cycle and predicting menstruation;
  • allowing you to override and mark your Peak day in a cycle;
  • identifying your Basic Infertile Pattern (BIP) whether you are having cycles or breastfeeding;
  • allowing you to override and define your Basic Infertile Pattern (BIP);
  • applying the 1,2,3 count of the Early Day Rule 3;
  • reminding you of the wait day after intercourse in the pre-ovulatory phase.
