Help me

So I've just started doing this bbt, how does it work, I've already ovulated as you can see, got a peak on my Lh test, I'm unsure for deffo if it was the 8th or the 9th if I properly ovulated as I had right sided pain from 8th all the way through to the 9th late night.so my temp was 36.6c or 97.88f
