OPK confusion!!

Hi girls!

I am on CD 11 and I took a clearblue advanced ovulation digital test and a cheap amazon ovulation strip this morning and both were negative.

At 5h30 PM, I took another amazon cheap ovulation test and it was positive... but the clearblue still gives me an empty circle....

I usually have 29-32 days cycle so I am very confused on which test is telling the truth?

In the picture, the top one is this morning 8h30AM and the bottom one is the same day 5PM.

Do you girls trust more the test lines or clearblue? Thanks!!
