Help please BFP OR BFN?

I am 11dpo and i made three pregnancy test today and all came back positive and even Cleardblue digital one said Positive so i desided to make pregnancy test later at night and it was invalid then i took another one close to midnight and i dont know i see a very faint line but earlier that day made same test and it was clear like sun but now you barely see it...This was last one i took... bfp or bfn or invalid?
