Ovulation testing daily?!?

Sherri • With the help of Glow, now pregnant with my third and final baby! :)
I took an ovulation test yesterday (Sunday) and I did have two lines but one was very faint. My highest chance of getting pregnant is Thusday. So I guess my question is: Do I need to take a test daily? I'm obviously fertile right now from the faint second line even though I'm not at the  "peak day." ( and yes I plan on being with my husband every night this week. )
