Clear blue 2 most fertile days Ovulation test.

Hi, I’m hoping some one can help, I’ve been testing using the clear blue 2 most fertile day ovulation tests. Yesterday morning, I done one and had a smiley face, which ones I’m having my LH surge right. But when I removed the test from the digital reader the lines looked like this. Tested again this morning and had just a circle, no smiley face. Does that mean I hit my lh surge yesterday?
