confused

So I've only recently started trying. The other day I had really light pink spotting which I googled and it said it could be an ovulation bleed. So I did an ovulation test and there was a line there but wasn't as dark as the control line I've been testing about 3 times a day for the last 2 days, wishful thinking I suppose, each one has time the line has been getting darker but still not as dark as the control line. Does anyone know what this could mean?
