Clear Blue (non-digital)

So yesterday I took a cheapy test and got a faint BFP. This morning I took a clear blue hpt and got a BFN
When I opened the clear blue test, the not pregnant line was already showing before I peed on it. Once I took the test the line turned blue. I was unsure if this was normal for this brand. Has anyone ever experienced this before?
I was excited yesterday, and now I'm so confused. 
AF was due yesterday. No sign of showing.
