Confusing Opk's!

So this morning I got the solid smiley on my clearblue advanced test, and my little test strips showed the test line as being almost (very close but just shy of a positive) as dark as the control line. I just tested again this evening and now both are negative.

The tests were about 10 hours apart. So does this mean I ovulated, or got close but nothing happened. I am very confused!!
