You can go to the store and buy ovulation sticks. They will tell you your most fertile times of the month. I don't know who told you it's impossible to track; it's easily done with items near the tampons/pads and condoms. It would be the most accurate considering your period only tells you that you missed the time when your egg was able to be fertilized.
