Any BBT Expertise would be great!

Here is my timeline hopefully this will be clear. Disclaimer: this is all tracked on the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow App</a>, so they provided me with ovulation date etc.
Ovulation: July 12 CD 12
Rise BBT: CD 18, 6DPO 98.30
Slight Dip: CD 20, 8DPO 98.18
Rise BBT: CD21, 9DPO 98.30
Then stays even for a few days.
Drop BBT: CD 24, 12DPO 98.23
Drop BBT: CD 25, 13DPO 97.94
Rise BBT: CD 26, 14DPO 98.06
I know they say that if your temp stays high you are more than likely pregnant. I tested at 9DPO and 11DPO got my BFN. I'm now waiting until I good time has passed where AF doesn't show up. Has anyone had any experience with dips and rises and gotten their BFP? I've also included my chart for visual. Any advice will be helpful!
