Know my body - premium insights
Tempdrop premium app subscription offers additional insights and data interpretation. Upgrade today and get a free trial for more from our all-in-one charting solution.
Ovulation and fertility window insights
See your fertile window and ovulation estimates (light green) and verification (dark green). Estimates are based on your unique past cycle history and then verified based on new data entered. Tap on the green window in the cycle wheel to see your estimate or interpretation for any cycle day. In the chart view, find the fertile window under the row labelled (F). For those with irregular cycles (turn on irregular cycles mode), estimates will not be provided, but the interpretation is still included. Read more about irregular cycles and Tempdrop here.
Cervical mucus is not required when using the app in KMB mode, but if entered, pre-ovulation cervical mucus data will be used to open the fertile window in real-time.
Temperature data interpretation
Temperatures jump and remain in a sustained higher range after ovulation occurs*.
To evaluate if a rise in temps can validate ovulation, scientifically-backed rules must be applied. Our premium option will automatically interpret your results for you. Once the rules have been met, a red horizontal line known as a cover line (used for temp range interpretation) will appear, and the days from the start of the upward shift will be counted.
Ovulation will be verified if the 4th and 5th high temps remain above the cover line.
Cervical mucus interpretation
Whenever possible, observing and charting cervical mucus is a valuable cross-check in confirming the fertile window and ovulation. In the lead-up to ovulation, cervical mucus generally increases in quantity and the quality changes to a more fertile type. After ovulation, it abruptly changes back to a non-fertile quality. The last day of observing fertile-type mucus before this abrupt change is known as "Peak day". Identifying peak day and then adding a count of 3 days in which there is no return of fertile-type mucus can assist in identifying ovulation and closing the fertile window. Automatic detection of peak day (appears as a 'P' on the chart) and adding the 3-day count is a premium feature.
Ovulation day indication
Estimated ovulation is indicated by a green dot with a white border. After a temperature shift is verified and sustained, ovulation day will be shown on the day before temps rise. Verified ovulation is shown as a solid green dot.
* An upward temperature shift can be influenced by other factors outside of ovulation. Cross-checking a temperature rise against other fertility signs is always recommended when making fertility decisions. Results can vary depending on individual circumstances.
