Please note that we cannot provide any kind of advice when it comes to combining medication with Natural Cycles as the impact of a specific medication on your body can be very individual and may depend on your medical history.
If you are taking any form of medication, we would advise you to speak to your healthcare professional to determine how this may impact your body and temperature. If you confirm 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, you should confirm whether the medication causes you to sleep more 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.
