Ovulation test

Sandra
So today is cd 10, I just took my last clomid pill yesterday. I went and bought a 7 pk of clear blue ovulation tests. My dr said I should ovulate sometime between the 7th and the 12th. Here's a pic of my test this morning, should I test everyday or every other day? I assume this line should get darker as the days go on? 
​Thanks for your help
