BBT Charting any help would be greatly appreciated

I have attached my bbt chart, this the first month I have actually been doing it religiously between 5.45am-6am. I’m also doing ovulation tests which have all been negative so far. Does my chart look right, I’m guessing I will have to do it for a couple of months for a better understanding. But was hoping at least one of you lovely ladies on here could give me some insight if I have ovulated? If my temp does continue to rise does that mean I ovulated cd14 or could I have already ovulated on CD12 or neither ???? 🤯 is it possible to ovulate with out getting a positive ovulation test. Ovulations test do work for me as I have had positives previously.
