Need help reading tests

So these are my logs of my ovulation strips. So lost on how to read them as far as i know i havent ovulated at all? Please tell me if i have? I started these tests about 14 days after my first day of period. And my last one was taken a few mins ago and im supposed to start in 8 days. Should i keep testing or do u think i ovulated hefore i logged? Im soook confised. And i have no idea shat the abreviations means so please forgive me
