Trigger shot help

Has anyone had the trigger shot, and tested out the trigger and get a negative test.and then 2 days later have a positive pregnancy test?? I’m 10dpo got a peak on opk 9-5-24 ( 12days past trigger) I finally got a negative test which means the trigger has left my system. But is it possible to get a positive after 2 days following a negative test.??? Help please. I’m losing hope. I did not test again. I am asking to see if anyone experienced this. Because I am hoping I will get a positive test in 2 days. I just got a negative test today which means trigger shot is out of my system.
