Menstrual cycles don't run like clockwork, and environmental and personal factors can cause a cycle to arrive earlier or later than expected. You may want to make sure that occasional irregularities in your cycles don't throw off your predictions. To do that, you can use Clue's 'cycle exclusion' feature.

What causes irregular cycles?

Levels of stress may affect aspects of the menstrual cycle like length and flow. Changes in sleep patterns, diet, jetlag, and medications, such as emergency contraceptives, are additional causes of irregular cycles.

Most cycles fluctuate, and few cycles are completely regular. But "skipped" cycles – or other unusual cycle lengths – could also be due to pregnancy, miscarriage, an underlying condition such as polycystic ovary syndrome (PCOS), a thyroid disorder or endometriosis. Consulting a doctor with any concerns is always a good idea.

Use Clue's 'cycle exclusion' feature to accommodate your changing cycle.

Here's how to exclude outlier cycles from Clue's calculations to help make your averages and Clue's predictions more accurate:

  1. Go to Analysis
  2. Select the cycle you want to exclude
  3. Tap "Exclude this cycle"
  4. Activate the "Exclude this cycle" feature at the top of the screen

You can also include an optional note which may be useful when reviewing past cycles, especially with your healthcare provider.
