Ovulating?

Amanda
I have one of those clearblue digital opk's. It went straight from the "low fertility" circle to the solid "peak fertility" circle, completely skipping the flashing smiley. When I took the strip out, it looked like the color ran, but I'm not sure if. I should read into it that much. 
That being said, and with the picture of my bbt chart, would you say I'm actually ovulating? The opk was done yesterday. It was only cd 12, and I didn't even think I was in my fertile window yet. I usually ovulate cd 14.
