Faint line.. but digi says no

This is my chart. It's in over ride mode due to my ovulation being dated by bloods. I have PCOS. I have been getting blank whites but yesterday and today I have gotten squinters using frer. So I did a digi and it came back no. My luteal phase is normally 13 days. The chart doesnt show expected t date as first month in a long time using it again. Anyone got any thoughts as to what's going on??

Plus it's given me a score of 80 For pregnancy.

Thank you guys!
