The data the computers use
... to differentiate between fertile and infertile days are based on a few biological facts underlying the female monthly cycle.
One menstrual cycle - one ovulation
Every woman ovulates only once in each cycle. If on the rare occasion two or more ovulations occur, they will occur within 24 hours. After ovulation, the egg can be fertilized for a maximum of 18 hours.
Male fertility and ovulation
After intercourse, male sperm will remain active and fertile in the female body for a maximum of 3-5 days.
Timing your ovulation
This means that there are six days in every cycle when a woman can get pregnant: five days before ovulation and on the day she ovulates.
