Clearblue Advanced Digital.. Help??

Ra
Yesterday, I took the clear blue advanced digital opk and it showed high fertility. This morning, it showed the same result. It was early so I took another around 3PM and that showed the solid smiley face (peak). I looked at the stick when I ejected it, even though I know they say not to, and it showed what looked like a dye bleed, so I used another tester around 6:15PM, and it showed negative. Did I have an LH surge? Has anyone else experienced this?
