Help, I’m so confused.

So come home to take test, photos included. I do one, it looks positive but the line doesn’t go all way down so I take FRER. It is negative, maybe a squintiest line but can tell. So I take another one of the internet cheapie- maybe a line but nowhere near the first.

Now I did all this with same cup urine (which was pretty pale because I drink a lot of water). So is the positive a fluke, are the other two?
