Note: this article applies to Cyclers using the app with a basal thermometer. If you use an Oura Ring, please refer to the Oura section of Cyclerpedia.
You can take your thermometer with you when you travel, so that you can keep measuring even while traveling!
It is okay to bring your thermometer with you through airport security, but we also recommend that you check with the airline that you’ll be using to be sure.
If you travel across several time zones and experience jet lag, we recommend that you exclude your temperatures during the first 1-2 days. After you have adjusted to the new time zone, you should measure as usual when you wake up in the morning. Remember to always exclude your temperature if you feel hungover, sick, have slept less than usual, or have slept in.
It's also good to know that traveling can be stressful on the body, which means that it can sometimes affect your cycle. For example, it could cause delayed ovulation, and therefore, some cycle irregularities.
If you don’t have an internet connection while using Natural Cycles, you will automatically enter Offline Mode, where your data will be saved until you are back online again. Your fertility status will show in orange color and display 'Use Protection' for users on NC° Birth Control, and 'Offline' for users on NC° Plan Pregnancy. Learn more about the Offline mode here.
When traveling, please ensure to bring your thermometer with you, and avoid switching thermometers. A basal thermometer is highly accurate, but from one thermometer to another thermometer, there can be a small difference in how each one measures. An example of this is if one of your thermometers is showing one temperature, the second can show a 0.1° C difference. As the app is looking for the smallest differences to be able to locate where you are in your cycle, having two thermometers can cause false temperature fluctuations, even if both of the thermometers are from us. If needed, you should only change thermometers at the beginning of a new cycle.
It is also good to always keep in mind that if you do not measure every day or sometimes need to exclude your temperature, Natural Cycles' effectiveness as a birth control will not be affected. Logging less temperature data means that you may experience a greater amount of red days, where protection is needed, and this may reduce your satisfaction with Natural Cycles. Learn more here.
