Another OPK Question

I just started using these yesterday. Following the suggestion in the instructions i have been testing right when i wake up. But, now I read online that this is no good because the surge is more likely to happen during the day?

So if this is true now my question is - Should i test again this afternoon? If I do I may have to buy another kit because I could run out of sticks. Or should I wait, skip tomorrow morning and test tomorrow afternoon? Will this result in me possibly missing my surge? Last thing - I am only on CD11 - I have a 28 day cylce so wouldn't this be early anyway?

Thanks ladies!

You're suppose to use them in the afternoon. I always used them around 1-2pm???
