Could it be!?

I am now on day 34 of a 32 day cycle and experiencing some signs of early pregnancy so around 5:30am this morning I woke up for my morning wee and HAD TO do a test. As my eyes were tired I decided that I was imagining a second line appearing and it was all in my head so I went back to sleep until 8:15am. I have just gone back to look at it and there is definitely a faint line there (slightly darker than what I had  'imagined' at 5:30am...could this be a true reading or did I leave it too long!?
