BFP or evaporation line??

Took a test this morning and looked like it would be nothing so I got back in bed for a bit. Got up about 45 minutes later and saw this. I know it's really faint but it's there. I'm trying not to get too excited, tried to schedule a blood test but the doctor is booked until next week. I am 11DPO
​I just don't know if it's my BFP or an evaporation line from waiting. It's exactly where the second line is supposed to be.
