OvaGraph is in the process of being retired as of December 1, 2025 due to resource constraints. To allow those who missed the initial cutoff to download their data, we are temporarily re-opening the OvaGraph website on the morning of Friday December 5th and will be shutting down OvaGraph permanently on the morning of Tuesday December 9th.

Please use this second, final window to download your cycles to your computer, and do not upload any additional data.

Additionally, we have launched a new Fertility Awareness Method charting app called Cyclisity that is available now on iPhones, in the US and Canada, for Fahrenheit. We are working to launch Cyclisity on Android, outside the US and Canada, and in Celsius in the coming months.

For instructions on how to download your OvaGraph data to your computer and also upload it to Cyclisity if you so choose, please email support@cyclisity.com and we will provide instructions.

Thank you for your patience and understanding during this transition.

Sincerely, Sabrina, Max, Toni and the entire Cyclisity team

What conditions might alter my basal body temperature and impact my chart?

There are many factors that can impact your basal body temperature. These include, but are not limited to:

Inconsistent sleep (for any reason)
Fever/Illness
Alcohol and/or Smoking
Medication
Change of sleep schedule/changes in your daily routine
Exercise
Stress

If you are worried that one of your readings might be 'incorrect' due to one of the factors listed above, we recommend that you chart the reading anyway, and add a 'Note' about it to your chart. If you decide that you don't want this reading included in the ovulation calculation, you can always check the 'Exclude from BBT-based interpretation' box.
