Positive for 3 days?

If never had a positive last more than a few hours before I thought I got my peak on cd 13 but then on cd 14 it looks darker than my initial peak and it’s still positive this morning when do you think I ovulate? I thought today was ovulation day but now I’m confused do I ovulate tomorrow ?

(I know lh strips don’t confirm ovulation they just warn you of the possibility of ovulation occurring)
