    There are many ways to test your ovulation period. The tool we offer here is calculated based on your menstrual cycle. If your period is not regular, you are suggested to use other ways such as monitoring your body's temperature (In general, if you find your temperature is not normal and increase especially in the morning after you get up, it hints your ovulation period is coming.), observing a sample of cervical mucus (If it's slippery, clear and stretchy just like the consistency of egg whites, you are more likely fertile), using the ovulation test paper or other ovulation prediction kits.
