Positive or negative?? Plz help!

Sammi
I'm 9dpo today and did a test, well......a few tests and at first I thought I could see a shadow of a line- a proper squinter. So..... I did another one with the same urine which is a fmu, anyway, same thing again, so I couldn't be sure. I then did a another test but with a different brand and there's a clear line??! 
Now it's doing my head in as I don't know which ones correct. Why is the line non existent on the same brand first two tests but but clear on a different one? Ive put the pics below so you can see what I mean but the shadow of a line on the first two tests isn't really visible in the pic, so any tweaks will be really appreciated 😊. I can't believe it could be a positive because I was told I don't have any eggs left!  I'm really bricking it here!
As you can see there's nothing really there except when I take it to natural light, I think there is perhaps a line?
This one is very clear but maybe it's a faulty test?
