PCOS and Charting

This is my first month charting my bbt and ovulation strips together. With PCOS you can’t rely on the strips so I got a thermometer and starting temping. Can someone just take a look at my chart and let me know if they think I ovulated on cd21? With my temp did I feel like I did I had cramping and a lot of cm discharge then. I’m nervous about my dip in my temp I had yesterday at 6dpo. I’m just wanting to hear other people’s opinions on my chart like I said this is my first time so I just want to make sure I’m reading everything

right, thank you in advance for the input!
