BBT help please

So this is my first time temping. According to CM and an LH strip my ovulation is recorded correctly on this chart. However, I would have guessed it was later based on the chart. I was expecting my period yesterday so that’s why I’m wondering.

I had a negative pregnancy test so I’m not super hopefully but I would like to know when I ovulated and I thought temping would help, but I’m more confused now.
