Bfp or evap? Need eyes please!

Hello ladies! I posted this in the ttc section and realised afterwards I shouldn't have done that so haven't had a lot of responses! I didn't mean to post it in there! I took a hpt today accidentally instead of my opk, saw a faint line and was confused because my opk's are getting darker where as this is really faint, then realised I had taken a hpt instead of my opk. I don't know if I'm seeing things but is this an evap or bfp? Or is there even anything there? Thanks in advance x ​​
