Preferences determine how Ovusoft interprets fertility signs and calculates your estimated day of ovulation in each cycle. The Preferences section provides great flexibility in how fertility information is analyzed. This section explains what each of the settings does and shows you what the default values are set to normally. Most preference settings are cycle-specific. This means that you can adjust preferences from one cycle to another. For example, you might wish to do this if in one cycle you want to skip taking your basal body temperature and rely exclusively on cervical fluid observations and return to using both in the next.
If you accidentally make changes to a cycle, you can correct the changes by clicking the Undo button.After making changes to a cycle, Ovusoft may recalculate that cycle to apply your changes.
