GOING CRAZY!!!!! when do I test??

Brittany • 20....married since 7.16.14. TTC #1.
Hello,
​So I have a 30-day cycle. I've never missed or had a late period before. AF was due august 1st but no sign of her..... I'm confused. I took multiple dollar tree brand hpt and what I thought were positives were actually evaps. Besides the missed period I've had sore sore nipples, nausea, fatigue, heartburn, lower abdominal "soft" cramps, headaches. When do I test??? Am I out this cycle??? Been TTC for a year.  I do not chart bbt and believe I ovulated July 16-17.
