Fertility Charting is a popular method of identifying the fertile and infertile days during your cycle using observations of simple body signs.  Frequently, charting involves recording your body temperature when you first wake up and the changes that occur in your cervical fluid throughout your cycle.  Toni Weschler's book Taking Charge of Your Fertility covers charting in great detail, and additional background information can be found in the Fertility FAQs available here.

Charting Options

TCOYF.com offers three charting options:

• Taking Charge of Your Fertility for Microsoft Windows:  This is the original PC-based TCOYF application that can be downloaded and installed on your Windows computer.  Once downloaded and installed, the software and data resides on your PC and does not require an Internet connection in order to be used.  A free 15-day trial is available by clicking this link.  
• Web-based Taking Charge of Your Fertility:  This is the new TCOYF application that runs in a web-browser.  The application is hosted and the data is stored on our website, therefore, it requires an Internet connection in order to be used.  You can access the application by clicking on My Fertility at the top of any page.  
• Manual Charting:  If you prefer to track your fertility signs by hand, we offer a selection of PDF-based charts from Toni's book for free download at this link.
