Ovulation?? Help Please!

Kay
I am confused as to if I have ovulated already this month or not. I am on my most fertile day according to glow 8/3 but as you can see my ovulation test is negative today. I plan to test one more time today. However, On 8/1 was the darkest my tests have been and I had EWCM on 8/1 and 8/2...is it possible that I still ovulated although my tests on 8/1 were not quite positive?!
