The Mira Basal Body thermometer is a convenient tool for tracking your menstrual cycle and fertility patterns through the measurement of your Basal Body Temperature (BBT). It offers quick and easy temperature readings in both Fahrenheit and Celsius, seamlessly integrates with the Mira App for data storage and insights, and provides historical BBT data and charts for visual tracking. Monitoring your BBT can help you recognize ovulation, with BBT typically rising during this period and ranging between 97°F (36.1°C) and 97.5°F (36.4°C) before ovulation and increasing to an average of 97.6°F (36.4°C) to 98.6°F (37°C) after ovulation. To accurately predict and confirm ovulation, the Mira Analyzer is recommended for identifying the most fertile days. Tracking your BBT for 3-6 cycles until the first day of your next period is advised for building patterns, and while BBT tracking is valuable, combining it with the Mira Analyzer enhances accuracy, as external factors like illness, stress, alcohol consumption, medical conditions, and medications can affect BBT.
