Ovulation???

for the last 5 months I've been testing ovulation and I'm not sure if I'm ovulating. I usually test everyday of my cycle to see when my highest lh levels are. In this picture are my last 3 days of testing. Would you consider the middle test to be a positive ovulation test? It's supposed to be ovulation week and I have never in 5 moths gotten a darker line then that. I know it's supposed to be as dark or darker than the control line but what do you think.
