Trigger or BFP?

I am currently 10dpo and 12 days past my Ovidrel trigger shot. I've been testing on ICs every day since I did the injection. The last line I could see without squinting was around 6dpo. The rest have been shadow "are they there or not?" lines. This afternoon I got a line that looked similar to the 6dpo one; faint but definitely there. I took a FRER and got an immediate (albeit faint) positive. Think it could still be the trigger or could this be a real BFP?

Edit: the ICs are in order from top to bottom. Top was at 5dpo, bottom was this afternoon, 10dpo.
