||-on the far right was three days ago
|||- in the middle yesterday's 
||||- on the far left is today's 
I posted and asked on day || if it was a possible + ovulation I was told overwhelmingly no and that I should be soon and the line needed to be darker. Before day || I had NO LINE. 
Day ||| the line looked similar so I thought maybe today I would have it but it got even lighter. My bazel temp went up the .5. Is it possible the the first one was ovulation, or that I missed it at work? I just don't understand. ?
