Why Hasn't My App Confirmed Ovulation? (App Stuck in Follicular Phase)
If you think you have already ovulated but your Tempdrop app still says you're in the follicular phase, or it shows that your fertile window is open, this usually means the app is waiting for more data to confirm ovulation.
How ovulation is confirmed in the app
To confirm ovulation and move from the follicular phase to the luteal phase, the app looks for a valid temperature shift.
A valid temperature shift requires at least 3 consecutive days of sustained, higher temperatures above the previous 6 temperatures.
When a temperature shift is identified, the app will show:
- A red coverline establishing your baseline.
- A series of sustained high temperatures above that coverline.
- A luteal phase count (numbers indicating how many days past ovulation you are).
If you do not see this pattern or the temperature shift is not considered valid, your chart will show that you are in the follicular phase. This suggests that ovulation may be delayed or that the temp shift is not clearly defined.
Already see a temperature shift?
If you’ve already noticed a temp rise but the app hasn’t confirmed ovulation, one possible reason is that the Cervical Mucus (CM) cross-check option is turned on.
When this setting is enabled (under Settings > App Settings), the app also uses a valid Peak Cervical Mucus day around the time of the temperature shift to confirm ovulation.
If a peak day cannot be found, the app will not confirm ovulation.
To help the app accurately detect a Peak day, you must log cervical mucus daily, including 'dry' or 'none' days.
If using this cross-check isn’t important to your needs, you can toggle this setting in the app and choose to only use temperatures to verify ovulation and move to the luteal phase.
Tracking cervical mucus helps you identify your fertile window in real-time. We recommend you continue to track your cervical mucus, even if you decide to switch off the cross-check setting in the app.
I have a peak day and a valid temperature shift, but I still don't see ovulation confirmed?
If your chart shows both a valid Peak Cervical Mucus day and a temperature shift, but the app still hasn’t confirmed ovulation, the timing between the two may be too far apart.
In typical cycles, these two signs appear close together. If they’re too far apart, the app takes a conservative approach and won’t confirm ovulation. This helps avoid incorrectly marking ovulation when the data may point to an unclear or atypical pattern.
Quick Check
| Question | If No | If Yes |
|---|---|---|
| Do you see a valid temperature shift with at least 3 temps above the previous 6? | No: Continue to wear your Tempdrop sensor to see if the temperature requirements are met in the next few days. | Yes: Check the Cross-Check setting in the app or look for a Peak Day. |
| Do you see a Peak Day (P123)? | No: Add in any cervical mucus observations you may have missed, including Dry/None days. | Yes: Check valid temp shift is identified. |
| Do you see a valid temp shift AND a Peak Day? | No: Ovulation is delayed, or the pattern is less clearly defined this cycle |
Yes: The timing between the two may be too far apart. If in doubt, please contact the support team: support@temp-drop.com |
