How is ovulation indicated on the fertility chart?
Ovulation dates are indicated by placing a dark outline around the date. If the ovulation date was automatically calculated, the outline will be black. If it is a manually specified ovulation date, the outline will be blue. Chart shading also offers an indication of when ovulation occurs on your chart based upon individual symptoms. You can also see the ovulation date highlighted on the various calendar displays. The Hormonal Forecaster desktop version similarly highlights the overall calculated ovulation date by circling the date at the bottom of the chart.
