Ovulation is confusing

Alisha • Tue, Aug 13

Okay so I took an ovulation test this early afternoon I think around noon and the strip said I was ovulating and I took one just now 9 hours later ish and it says I'm not my question is can you ovulate only certain times of the day or do you ovulate all day? Help ,😭 I'll test tomorrow and next day as glow says my highest day is Wednesday.
