Too early to test??

Alexis
I believe I ovulated 6/12/16-6/13/16 and had sex 6/11/16 and 6/12/16. I had a solid smiley on 6/12/16 and 5 days of blinking smileys prior. I tested last night and got a clear as day negative pregnancy test, very anxious when should I test again?! Apps tell me my period is due anytime between 26th-28th
