So I took this ovulation test Friday around lunch time and it wasn’t dark right after I took it (like seconds)

so I left it on the counter and when I went back to pee that same day just a few hours later it looked like this? I feel like it’s positive ( it’s the only one I have) and back when I used pregmates strips ( which I love as well) I could get a positive and look at it hours later and it would still be the same color as when I first took it. My question is could the color be a true positive opk or it just looked like that bc it was hours later?
