Clearblue Ovulation Test questions

Ok those of you that have used the digital Clearblue ovulation tests, when did you test? Every other ovulation test I've used say mid afternoon but these say any time as long as its the same time every day. I've been getting home later this month than usual so it's been after 5 when I've been testing so I wasn't sure if that's go late. I'm in cd 14 and still no surge but that's kind of what I expected bc last month I didn't get a positive until cd16 with my cheapo ovulation tests.
