How to deal with missing data? First, consider where you are in your cycle.
- If you've already observed 3 high temperatures and no mucus, indicating that ovulation has occurred, and you haven't gotten your next period yet, a missing temperature doesn't matter.
- If you are in the very beginning of your cycle, the missing temperature probably won't matter. Wait until you see signs of ovulation - at that point, if the missing temperature is more than 6 days prior to ovulation, it doesn't matter.
- If the missing temperature is within 6 days of when you think you've ovulated, or it's in the 3 days you are looking for higher temperatures to indicate ovulation has taken place, proceed with caution! If there's only one missing temperature, add an extra day of abstinence. If there's multiple missing temperatures, proceed with even more caution.
Happy New Year!
