To forecast ovulation Period Tracker calculates 14 days before the projected start date of one's next period. Forecast accuracy depends on a number of factors including how regular one's cycle length is, when one actually ovulates during the cycle, and how many periods have been logged in the app. Anxiety, stress, diet, nutrition, exercise, environment, medications, age and other factors can also affect one's cycle from month to month.

    it's great to have my "." date projected for me so I don't have to do it myself. Plus, the app is pretty accurate.. It's either 100% correct or 1-2 days off. Thank you
