To get the most out of the app, we recommend logging temperature data throughout your entire cycle, including during your period. Aim to add at least five temperatures every week.
Logging temperatures regularly and often provides the algorithm with the maximum amount of data about your cycles, which significantly improves its ability to isolate your fertile window. If you are using NC° Birth Control, you’re likely to get more Green Days during your cycles. If you are using NC° Plan Pregnancy, this helps the app narrow down your fertile window, optimizing your chances of conceiving.
However, it is okay to miss a temperature here and there – forgetting to measure (or wear your wearable device) doesn’t affect how effective NC° Birth Control is at preventing pregnancy.
Even if you don’t add your temperature on a day during your period, we still recommend that you open the app and log Period for that day.
