Tool 1 · Chart analysis

Analyze your chart

Enter your basal temperatures (taken on waking, before getting up) and, if you have them, your ovulation (LH) tests. Everything runs entirely in your browser: no data is sent to a server.

FertiLuna is not a medical device. Results are indicative and do not replace the advice of a healthcare professional.

Manual adjustment (if the automatic reading gets it wrong)
Series:
  1. Calibrate the day axis (2 clicks on the ZT/day line).
  2. Calibrate the value axis of the chosen series. Note that BBT and LH are often on opposite axes.
  3. Click the series' curve to pick up its color.
  4. Switch series for the second curve, or import.
