Help trigger shot question

Rebecca

So my boobs have been sore since 3dpt and im now at 10 and they still hurt ive also been extremely bloated lately but i know the trigger shot mimics pregnancy symptoms. I took a test on 8dpt testing my shot out and the line was still there but faint, took one on 9dpt around the same time and it almost looks like

9dpt line is darker maybe? Tested again today at 10dpt and still a line. Could this be the start of my bfp or just the trigger shot??
