Im super confused, BFP or BFN?

Shalese

So yesterday I took a pregnancy test and there was a really faint BFP. After some time it got darker so I was pretty convinced. However this morning I took the same test and it came up negative. I went to the dollar store for the cheap pregnancy tests and both turned positive after the allotted time, about 6 minutes after, but the test says it’s invalid after 5 😩. I don’t think it’s an evaporates line because they’re colored. Ugghhh!!!! I’m tormented waited for AF, which should be here tomorrow.
