Why did I get a negative hpt and 6 positives?

Well I got a bfp 2 days ago the line was very faint I was only 9dpo, since then I have taken 5 more and they all show up positive still faint but very clear there is a second blue line there. I bought one at family dollar yesterday and took it and not with fmu and it came up negative. It kind of has me worried, anyone else have this happen??? Its not possible to get 6 false positives right I really need some personal experience or reurance!
