I did that too. My test line was almost as dark as the control line. So then I tested the next night, and the test line was fading.
So I would say you're getting close to ovulating, but not there yet. Keep testing!
{The pic was very small for me but going from what you wrote}
From my understanding, both lines have to be dark to indicate O coming, but I noticed that from my own experience & what I've read of others, if the other line is faint it's still a negative however an indication of an O to come soon so you may want to test more frequent (like twice a day, mainly late afternoon & evening). I was getting faint lines for a few days then wham both lines were dark, then next day faint again.
