Help - ovulation test

Summer
Hi! 
So I should be ovulating within the next few days, but this is my first month taking ovulation strips.
I bought the clearblue digital, and clearblue said I am not ovulating today...but what I'm curious about is the fact that yesterday when I ejected my test, there was only one line. Today, there are two definitive lines.
Does this mean I'm about to ovulate? I know the first line has to be darker than the second...anyway, any help you can provide is appreciated. I'm a newbie!
Also: no I didn't pee in the car. 😜
