11 days past Trigger shot

Ashley

So I took a trigger shot 11 days ago and this morning when I took a HPT it was extremely dark. I didn’t test it out but 4 days ago had a much lighter line on a blue dye test. What do you guys think? Could the trigger still be this dark at 11 days past or could this be my BFP. We think I possibly ovulated before the trigger. So if I did I’m 15 dpo one day late on my period. If not I’m 10dpo *picture was taken within 5 minutes. I bought first response
