BBT (Basal Body Temperature) monitoring
Basal Body Temperature (BBT) monitoring involves consistently measuring your body's lowest resting temperature, typically taken each morning before getting out of bed. Slight hormonal changes, especially a rise in progesterone after ovulation, cause a small increase in BBT—about 0.5°F (0.3°C). Tracking these temperature shifts over time helps identify ovulation patterns, which can be useful for conception or understanding menstrual health. Using a precise digital thermometer and recording your daily readings creates a temperature chart that reveals fertility windows, aiding women in planning or understanding their menstrual cycle better.
