Trigger and HPT

Dee
      Hi ladies! I had my trigger shot (ovidrel) on Thursday may 28 (13 days ago) and an iui Saturday may 30. This is my third round of iui and first round of ovidrel. 
     I didn't test out the trigger. Starting at 9 dpo, I took a hpt. There was a very very faint positive. I took another yesterday and one today (11 Dpo). I took pics. Do you think it's still the trigger or I have a bfp
     I have my beta on Friday. Should I go in tomorrow if I think it's positive? They said they would take me one day early. 
     The bottom hpt is yesterday and the top is today's.
