Testing out trigger shot...

Is it normal that I tested for the first time this morning (I triggered last Thursday night so it’s almost been a week since it is Thursday AM here) and the test is completely negative? I was planning on testing for a few days in a row until the tests are negative to make sure the trigger shot is out but it appears it already it. I’m only 7 days past trigger, 5 dpo. Makes me worried it didn’t work.
