New to charting and need help

*D*
I don't know what I'm looking at here. When did I ovulate? I'm still getting positive OPK (the Answer stick ones with double lines). I took my temp today at normal time 6am temp was 97.7, immediately fell back to sleep till 1:30.  I took temp again and it's 98.3 now. I logged the first temperature. When did I ovulate, if at all?
