What is the difference between Likely Ovulation Day and Possible Ovulation Day?
If your Chart Settings is set to FAM Mode: OvaGraph is designed to display the Likely Ovulation day and coverline when a verified temperature shift is detected while you are seeing fertile quality cervical mucus/fluid and experience lubricative vaginal sensation. However, as you move through your cycle, OvaGraph will continue to monitor your BBT and cervical mucus data. If a second possible temperature rise is detected, your Likely Ovulation day will shift accordingly. If this happens, you will see a solid purple line marked as the ‘Likely Ovulation Day’, and a light purple shading marking the ‘Possible Ovulation Day’.
If your Chart Settings is set to BBT Mode: OvaGraph is designed to display the Likely Ovulation day and coverline with the first verified temperature shift it detects. However, as you move through your cycle, OvaGraph will continue to monitor your BBT data, and will continue to look for another temperature shift. If a second temperature rise is detected, your calculated ovulation day will shift accordingly.
