Trigger or positive?


I'm 10 dpt and 9 dpo. I tested out my 5000 iU trigger shot with cheap pregnancy tests, and it was out of my system according to those by Saturday, Aug. 21 (2 days ago). I took a FRER and a cheap test this morning. Got a negative on the cheap test, but got this faint line on FRER. Could this be leftover trigger or a positive? I know I need to test tomorrow or the next day to be sure, but insight appreciated!
