What do the colors in the Calendar mean?
Colors in the calendar indicate that a certain day is a fertile day, a period day, or neither. A day colored pink is an expected period day and a day colored green is an expected fertile window day. All other days are colored blue or not colored depending on your calendar view. Days in the future will be colored with our best guess based on the data you’ve given us and our algorithms.
