Ok please help!

I took a pt with fmu this morning. I got in the shower for like 5 minutes. Got out and looked at it. It was a very very very faint almost not even blue line in the postive side and a very blue line in the negative sign. (First response test). I just went to pee and when I wiped it was very light pink on the toilet paper. I am 11 dpo. But just took another test and bfn :(
