The predicted ovulation day that you see in your Clue app is only an estimate. We recommend using the results of ovulation tests to determine your exact ovulation day.
Tracking positive ovulation results over multiple cycles allows the app to predict your ovulation more accurately in the future. This is because Clue can learn how long your luteal phase typically is. The luteal phase is the time from your ovulation until the start of your next period.
To enter an ovulation test result, follow these steps:
- Open your Clue app.
- Tap on Track, or go to the Calendar View.
- Tap the day you want to enter your test result.
- On Calendar View, you will need to double tap.
- Tap the ‘Tests’ category.
- If you don’t have the ‘Tests’ category visible yet, follow the steps here.
- Select either ‘Ovulation Test Pos.’ or ‘Ovulation Test Neg.’.
- For iOS: Tap ‘Done’ in the top right-hand corner to save your test result.
For Android: Tap ‘←’ in the top left-hand corner to save your test result.
When you enter a positive test result, it will set your day of ovulation to the day after your result. This is because over-the-counter ovulation tests indicate ovulation is within 24–48 hours of the result.
We’d like to highlight that the predicted ovulation day in the Clue app should not be used to prevent pregnancy. It’s not designed to be used as birth control. It is only an estimation and not clinically validated.
