Bbt
A precise tool.
What is the Bbt & How does it work?
Basal Body Temperature (BBT) is the lowest body temperature attained during rest, typically measured immediately after waking.
Tracking BBT across a menstrual cycle reveals a subtle rise of about 0.3β0.5β―Β°C after ovulation, providing a natural indicator of the fertile window.
\Delta T = T_{\text{fertile}} – T_{\text{preovulatory}}
ΞT = temperature rise after ovulation
Consistent daily measurements, combined with cycle day information, enable users to predict upcoming ovulation and better understand their reproductive health.
