Has this happened to anyone before? Or do all ovulation tests do this?

I'm 9DPO and tested with a boots pregnancy test which was negative. But I done another ovulation test just to make sure they told me the truth 9 days ago. They're the clear blue ovulation tests. Give you a smiley face when ovulating and a circle when not ovulating.

9 days ago I had a smiley face and the following day I had a smiley face, the line on stick (look at photo) were visually positive as well.

The ovulation test I've just taken was negative on the clear blue monitor but when I removed the stick which you have to when used, there was two lines, one very faint. Could it be picking up early pregnancy?
