A word of caution about fertility charting sites and apps:
There are a variety of charting websites and apps available, with new ones emerging all the time. Many cannot be used to keep an accurate Billings Ovulation Method® chart. The site or app may restrict users to a limited number of predetermined sensation and/or mucus descriptions. Some apps classify mucus as fertile or infertile in a way that contradicts the research on cervical mucus that is the foundation for the Billings Ovulation Method®.
