Why aren’t my cycle predictions accurate?

If your cycle predictions seem inaccurate, it may be that an atypical cycle is affecting Clue’s calculations. Experiences like pregnancy, miscarriage, use of emergency contraception, abortion, or using hormonal birth control to skip a period can lead to one of your cycles being much longer or shorter than what is typical for you. 

To get your predictions back on track, you may find it helpful to log an atypical cycle and exclude it from Clue's calculations. By excluding a cycle, your atypical cycle length won’t be used when calculating your upcoming cycle predictions. We understand you may not want to erase your experience from your app history, so you can add a personalized note to the cycle to keep a log of why you decided to exclude it from Clue’s calculations.

To exclude a cycle from Clue’s calculations, follow these steps:

  1. Open your Clue app.
  2. Go to the Analysis Tab. 
  3. Scroll down to “Your cycle history” and tap the cycle you want to exclude.
  4. Toggle on “Exclude this cycle’s data from Clue’s calculations” and add an optional note about why you excluded the cycle.

If you want to include this cycle in your calculations again, just go back and toggle off the button.
