Easy to use
When you first receive the device the time, date and year are already pre-set.
1) Set the alarm for what time you want to wake in the morning.
2) Every morning, before getting up or becoming active in any way, take your temperature, by placing the sensor under your tongue for 30-60 seconds. It will beep once your temperature has been recorded.
3) Press the + (Yes) or – (No) buttons when pearly® asks if you are “M” menstruating.
For women with relatively stable cycles, the fertile days can be narrowed down to fewer days than for women who have fluctuating cycles. The average woman has 6 days during a 28 day cycle where she can fall pregnant. pearly® is used as a means to better plan your sexual activities, for planning or avoiding a pregnancy.
The temperature reading values are calculated and are shown on a daily display – it could not be easier:
Red = Ovulating/fertile
Yellow = Learning your cycle – usually at the beginning of use or when missing regular temperature readings
Green = Infertile
