Main highlights

•TRACK AND MONITOR OVULATION — Consistent monitoring of your basal body temperature helps identify when you are ovulating, allowing you to best identify your optimal fertility window.
•HOW BASAL THERMOMETERS WORK — Body temperature rises slightly during ovulation; by tracking your basal temperature, (your at-rest temperature), you can detect when you are expected to ovulate which may aid in predicting fertility. Consult with your healthcare professional for detailed guidance.
•BEST PRACTICES — Basal body temperature means your ‘at-rest’ temperature; to optimize your results, use daily at the same time, ideally immediately upon waking and before leaving your bed. Use the included tracker or other method to note all temperature digits to the 1/100th of a degree. A slight increase in temperature may indicate ovulation and when you can expect optimum fertility.
