Am I seeing things?!?

Chelsea
Ok so usually I can tell when the lines on my opks are the same color.... But I'm second guessing my eyes this morning. According to glow and ovia my fertile week is supposed to just be starting TODAY!! 
I've been taking opks for the last week and it wasn't till yester that I really could see any sort of a line at all. So I thought all was right on track...
But is this one positive??? Or will it be positive in the next day or two?
