I get faint lines for a few days around ov..they have never ever been exactly the same thickness or darkness but definatley are not there when I am not ovulating. I got them the cycle we got pregnant for 3 days only then they went away till 14 days and appeared again when I used opk as hpt.

I take any line aorund that sort of a time as indication it may be happening I have spoken to others who have never gotten a true positive and have ovulated. I use the ovunow internet cheapeis it maybe different for other brands ( great for poas addcits like me)
