BBT Chart Confusion!

Cindy • 25 yrs. TTC baby #1 for 3 yrs now. PCOS. Baby dust to you all! ✨
Ok ladies so it's my first cycle attempting to chart my temp. Here's what I got so far I've been taking my temp everyday between 8:30-9 am. Can anyone interpret or explain the main points. I want to know how you can tell if you ovulated or not. I know I have to chart more but I just need some help!
