this tool you can calculate your fertile days. These
are the days around your ovulation day. In this period,
the probability of becoming pregnant is at its highest.
would like to point out expressly here that the reverse
conclusion is not valid! You can very well become
pregnant also before or after these days! The calculated
dates cannot therefore be used for contraception purposes.
The risk of becoming pregnant before and after these
calculated days is approximately 30 percent!
Between these days and immediately before them, the
probability of becoming pregnant is at maximum.
