Positive on bottom test?

I'm 10dpo but I had a trigger shot. I've been testing since 7dpo and had negative tests previously so I think the trigger shot has left my system. The top two are from the last two days and the bottom is today. Is it really a faint positive or still from the trigger? I'm getting a blood test Monday with my doctor but just curious what's going on in the meantime. Thanks!
