Frequently Asked Questions (FAQs)

1. Are fertility thermometers accurate?

On some BBT thermometers, the packaging boasts of accuracy to 1/100th of a degree. For example, the reading will give you 98.63 degrees F instead of only 98.6 F. However, to chart your BBT and predict ovulation, you don't need this level of detail; all you need is an accurate reading to the tenth degree.

2. What are fertility thermometers?

Using a basal thermometer allows you to take your temperature and keep track of your readings. This lets you find out when you ovulate and what your cycle typically looks like over the course of a few months so that you can plan to have sex during your most fertile time.
