Ovulation tests & AF confusion! Please help

So AF is 10 days late (neg hpt) I ordered some ovulation tests and today I tried one, it had a faint line (see pic) I know the line has to be same or darker than the control line so I know I'm not ovulating right now but am I soon?? Surely I shouldn't be?  This is all so very confusing! 
​Any insight or advice very welcome!
