When to test??

Kelleyanne • Mommy to Brianne Kathleen ❤️And baby in May 2017 ❤️
This is my first month TTC baby number two. I believe I ovulated anywhere from June 26-29. Curiosity got the best of me and I tested yesterday.(negative). I have the clear blue tests that say the earliest I should test is tomorrow. Has anyone had any success with testing before missed period or should I wait, and if it is negative  is all hope lost this month? Period is due 12 or 13 of this month.
