Help! OPK question

Before anyone says anything. I know the bottom two tests are positive. The top two were taken yesterday. The first top photo was at the 5 min mark, the second top photo at the 15 min mark. The first bottom photo is before 5 min mark and second bottom photo is right at 5 min mark. Yet glow (after scanning photos of my tests) is saying positive for yesterday’s tests (top 2) too! So when will I be ovulating if their both positive?
