You
have to begin to count the cycle from the first day of the
menstruation to the end. Normally the standard cycle is 28
days, but it can fluctuate between 23 and 35 days, so there
so much variation between the duration of them, in different
women. You have to know that the number of fertile days can
change from one woman to another, or even in the same woman,
depending on external circumstances, like stress, state of
mind etc..., that´s the reason, we recommend a daily
monitoring to the right use of it.
With
this strip control, you will obtain a planning which will
help you to understand your fertile and non fertile days with
a high level of accuracy, if the days of your cycle don´t
fit in with this strip, you can make a new strip with the
days of the duration of your cycle, making copies for each
new cycle or keep in touch with us, and we will help you.
