BBT HELLP?!

Heaven • Expecting #1 December 2021

(Ignore everything before the 26th because my cycle itself was a hot, hot mess!!!) AF was the 25th-28th. My opk peak was on the 10th...but I haven’t gotten a BBT spike since. My PDG strips confirm the ovulation tho. Is there any reason my temp wouldn’t spike? I’m 3dpo today
