Medication can affect your temperature. If you take regular medication or anti-pyretics (fever reducing substances), it’s worth consulting with your doctor to discover its impact on your body temperature.
A healthcare professional must evaluate your unique history and set of circumstances before advice is given.
If you get confirmation that the medication impacts your temperature and if the medication is active in your system when you measure in the morning, you should exclude your temperature that day.
Additionally, if you measure using a basal thermometer (note this does not apply to using the Oura Ring) you should confirm whether the medication causes you to sleep more or less than usual, as this may affect your temperature. You still need to measure at the same time (±2h) as you usually do. If you sleep longer than usual, you should set the alarm to the time you usually measure your temperature and continue to measure as before.
You should also clarify with your healthcare professional whether or not your medication affects your cycle. Natural Cycles should not be used alongside any kind of medication or hormones that could affect your cycle.
