BBT charting is confusing, HELP please?!?

Rebecca

I started charting a little late in this cycle, but I wanted to see if my charts had changed from when I was TTC over 7 years ago. The first 2 high spikes are from temping later in the morning. GLOW keeps changing my ovulation dates?!? I had positive OPK tests from 21-23. My big concern is from the temperatures it doesn’t look like I’m producing enough progesterone, or maybe I am?? Confused.... did I actually ovulate?
