Tempdrop temps vs oral thermometer results, should they match?

If you are already using a traditional BBT thermometer*, you may want to cross-check the results for a cycle or two to ensure Tempdrop is working well for you. 

Tempdrop results in comparison to oral temperatures
  • Traditional BBT temp results can be higher or lower than Tempdrop
  • Compare the pattern of both sets of temps over the course of the cycle - not each individual day

Will my Tempdrop vs traditional thermometer results be the same each day?

No. Tempdrop can read in a different range (higher or lower) than a traditional BBT reading. Tempdrop is a different type of thermometer and captures a sleeping temperature result instead of a waking temperature. 

Look for the pattern over the course of your cycle rather than compare each day. 

Will my temp shift day match with both sets of results each cycle? 

Not always, but this doesn't mean there is a problem.

A difference of a day or two in shifts between thermometers is not unusual. 

Charting your fertility signs will not narrow your ovulation down to a specific day. Instead, it gives you information to help identify the ovulation window (approximately where ovulation occurred). Cross-checking your shift with other fertility signs, such as LH and CM will help you understand if your temp rise is connected to your ovulation event.

*Traditional BBT temperature might be taken orally, vaginally or rectally.
