Note: this article is only applicable for Cyclers who are using Natural Cycles with a basal thermometer. If you are using Natural Cycles with an Oura Ring or Apple Watch, you should not see any black data – please refer to the Oura or Apple Watch sections of Cyclerpedia for any help.
When you first start using Natural Cycles with a basal thermometer, you will not be able to see your fertility status right away. Instead of red and green days, your data will show in black until you log your first temperature because your temperature is the main data that the app uses to calculate your fertility.

Once you receive your thermometer and add your first temperature data, this will unlock your fertility status so that you can see if you have a red or green day!
