Is this still the trigger?

So I started testing out my trigger around 5dpo. I’m now 8dpo but I did the trigger shot like 9.5 days ago. I took both bottom tests today, one first thing in the morning and the other in the afternoon. Usually when I do the trigger it’s basically nonexistent on the tests 8 days later and completely stark white by day 9. Obviously I was surprised to see anything at all on the cheap tests so I decided to do a frer a few hours after the afternoon test and there’s nothing there at all. And now I’m confused. Isn’t the frer supposed to be more sensitive? Is the trigger shot still in my system even though it never has been this long before? Has anyone experienced anything similar? How did it turn out for you??
