Petit Sophia is an advanced Basal Body Temperature Thermometer for women who prefer to manually chart their menstrual cycles to determine fertility and ovulation for planning pregnancy and for timing conception.

Measured immediately upon waking, when the body has rested for a minimun of six hours, Basal Body Temperature varies slightly from person to person. However, for most women, 96 to 98 degrees taken orally is considered normal before ovulation and 97 to 99 degrees following ovulation.

Designed specifically to measure subtle rises in BBT — which typicaly range from 0.5°F to 1.0°F degrees, Petit Sophia's compact size and easy-to-read digital format provides an exceptional tool to assist with traditional Fertility Awareness / Natural Family Planning methods.

Whether you are using the Billings Method (cervical mucus and position observation) combined with BBT readings, or the standard Sympto-Thermal Method, Petit Sophia will offer unparalleled accuracy to facilitate your efforts.
