Positive OPK?

Excuse my dirty sink 🫣 pic is from CD14 @ 9:30pm, to me it looked ALMOST positive but not quite, now I’m on CD16 and they seem to be getting lighter.. CD14 was the darkest I got. Been BD every other day since CD8, not sure if I missed my peak and ovulated already or if I should keep testing and waiting for a darker test 😩
