Help!

So I took an ovulation test (ClearBlue) and I have a faint blue line and a dark blue line. According to the box my LH Surge is low, so does this mean I'm close to ovulating? If I were to take an ovulation over the next few days will my LH surge get higher and I'll get two dark blue lines? I'm so irregular with my periods and could never pinpoint when I'm ovulating. I've taken tests before sand only got one line. This is the first time I've gotten a second faint line and I don't want to psych myself out.
