So I took this test and this line showed up in the time frame, with a small spot of it being very dark and the rest faint. I took this picture at 10 minutes. It is a full like although I'm sure the picture won't show it very well. Anyways, I'm not sure if I should believe it is positive, 1) because when I woke up several hours later(took the test at 3am), the line was  pretty much gone. And 2) because I took a clear blue +/- with smu and it was negative. I'm 11dpo with a 12 day LP. Anyone ever have this happen? What was your final result?
