Frequently asked questions
When travelling outside Europe:
The time differences on long-haul journeys are for the most part so great
that your wake-up time is outside the "time window" in which cyclotest®
baby accepts your measurement. In such cases please contact the
cyclotest® service hotline in good time.
The female cycle
The female cycle is 28-29 days. Deviations of up to 5 days are consid-
ered to be within the normal standard range.
There are three distinct phases here:
• a relatively short infertile phase which begins with menstruation
• a fertile phase which ends shortly after ovulation
• a relatively long infertile phase after ovulation

Menstruation
The temperature method, which is based on the comparative meas-
urement of the wake-up temperature during a woman's individual
cycle phases, allows conclusions to be drawn about the processes in
a woman's body. The more temperature values and information on
the cycle duration are available, the narrower the start and end of the
fertile phase can be pinpointed.
