What is going on with my tests!? Anyone used 'PregSeen' before?

I feel like I'm going crazy... ! We have been ttc for 9 months, and I finally got my bfp at 11dpo yday. I did a few yday and 1 today and all faint but there. I had ordered some from Amazon a while ago - 'PregSeen' tests and just done it and it's negative... my last bfp was 6 hours ago. Could this be a chemical, but could it have disappeared SO quickly or is it a dodgy test?

Which one is negative? I think I can see a line on all of them, although the blue one under the clear blue tests is very faint.

Oh sorry, I should have said, I didnt get a pic of the negative one, it annoyed me so I took it apart to investigate and then chucked it haha. But it was defo negative, but it did just look a bit off to be fair, like the control line was wonky and stuff. Is 11/12dpo still a reasonable time to be getting lines that are on the fainter side?
Those pics make the lines look fainter than they are i think.

Sounds like a dodgy test then; you've had several BFPs, I mean this really kindly but taking more tests won't change anything so I'd step away from those now (or limit yourself to say one a week if that feels too hard). I say this as someone who has had multiple early losses so I understand the urge to keep testing, but it doesn't really help, just feeds the anxiety.
