Generally speaking, ovulation usually occurs 14 days after the beginning of your menstrual cycle, (your menstrual period being day one) Your 'fertile' period would start 4-5 days prior to ovulation, as that is how long sperm can 'survive' to 24-48 hours after, as that is how long the egg 'survives'.
