This is the most fertile period of your cycle: during ovulation your chances of conception are highest.he time of ovulation within the menstrual cycle is determined by the luteal phase, which is usually 12 to 16 days long. You can calculate the time of ovulation within your cycle by subtracting the length of your luteal phase from the length of your cycle.
