Positive or not?

This is the darkest line I’ve got out of all the tests. It was taken in the morning on CD 19 - 3/2/19 (my cycle is around 30-34days). I test at least twice a day but all other times only got a faint line. Is it possible i’ve missed the surge? very faint line result for both tests Am & PM today.

Have BD since period ended on 20/1 (and during fertile window BD 29th, 31th, 2nd, 3th). 3/2 was estimated ovulation on FLO, and 4/2 ovulation from GLOW. Is this enough BD?
