Medication can affect your temperature. If you take regular medication or antipyretics (fever-reducing substances), it’s worth consulting with your doctor to discover their impact on your body temperature.
A healthcare professional must evaluate your unique history and circumstances before giving advice.
If you receive confirmation that the medication impacts your temperature and if the medication is active in your system overnight (wearables) or when you measure in the morning (thermometers), you should exclude your temperature that day.
You should also clarify with your healthcare professional whether or not your medication affects your overall menstrual cycle. You should not use Natural Cycles alongside any medication or hormones that could disrupt or affect your cycle.
Basal Thermometer Users Only: Additionally, if you measure with a basal thermometer, confirm with your doctor whether the medication causes you to sleep more or less than usual. Since consistency is key for basal temperature readings, you must continue to measure at your usual time (±2h), even if you sleep longer or shorter than normal. If you tend to oversleep, set an alarm for when you typically measure your temperature.
