Pregnancy test

Jodie

So please bare with me, Wednesday I took a clear blue test as I'm feeling a little off. It came back with a faint line for positive, I was unsure if it was an indent line. I bought a different pregnancy tes with pink dye tested on Thursday and it came back with a vvvvvvvvfl, it shows if you catch it in the right spot of light. MY husband can just make it out, what are the odds of different brands showing a false positive? My husband and I have been trying for 10 years, so we're not counting our chickens yet. I plan on testing on Sunday.
