Yes all that is one of the annoying-er elements of the Clearblues and why I am not the biggest fan of them.
As you already know you can't keep testing for 48 hours after it thinks it detects ovulation so if you have a false surge then you can end up thinking you've ovulated when it hasn't even happened yet.
BUT, you also can't just get a new tester either because it detects changes in your hormones. So it "thinks" it's starting off with you early in the month and even if you're totally surging right that minute, it will register negative. Starting a Clearblue with the sticks and the reader in the middle of the month doesn't work, unfortunately (and they should really have copious warnings about that on the box or in the directions but they don't. :/)
And since you have kept testing, it's picking something up, a rise in hormones from where you were. But remember it thought you were at negative (and you may have been surging OR at high fertility really) and has now detected an increase in hormones, you may be surging now. I would have another attempt to cover and then see what happens. Since you have the test already keep testing. If you get a positive within 2 days of having attempt, stick with this attempt, if 4 or more days have another attempt, if 3 either follow your gut or flip a coin (I think we already talked about all this! :))
