Ovidrel trigger shot

I’m 12 days past taking the trigger shot (Nov 7th) and just read two negative tests. I WAS checking to see that its out of my system but now I have a sinking feeling the shot didn’t work. My period is expected between the 24th-26th of Nov. Did anyone else feel this way? Should I have any hope at all for this round? This is all so confusing and hard on the heart!
