Faulty tests or this is really positive ?

I had a miscarriage in January and had spotting up until February 20th, no idea when conception would be but I would imagine that I would have to be very very early if this is real. I took two dollar tests, first one I though was maybe just an indent, then the second one had a bit darker of a line. So Followed by 3 first response all with faint lines. So I’m debating if this is really for real or just bad tests. I want to think there is no way all 5 tests could be wrong but I know first response has a lot of issues with being faulty lately. The lines do have color, just difficult trying to get a good picture without a glare.
