Help..

Okay so I took a clear blue early result pregnancy test (the one with the plus sign) and got a faint but definitely there line. Then, later that night, I took a digital test and got a bfn. So the next morning I took another clear blue and got another faint line. 2 days later I took the digital again and got another bfn. 3 days after that I took a dollar store brand and got a bfn. Then this morning I also got a bfn off a dollar store brand. Af is due on 7/17, so I haven't missed a period yet. But I got those two positives so now I'm really confused. 😔
