Ovulation test question!

Lynzee • Mommy to Ammarie, born on March 3,2016!
Yesterday, I took one and it didn't have a test line at all, today there's s faint one. (I took one yesterday about 8 o'clock and it was negative as well) 
So, I'm assuming that means I'm getting close to ovulation? Should o start taking one in the morning, and one in the afternoon so I don't miss my surge?
