Hi all, hope all are well. My GF today did a clearblue test which within the first 3-5 minutes came up negative. After approximately 10 minutes there was then a vertical line. Both lines were the same colour of blue with the vertical line being slightly thinner. About 1hr after she decided to do a clearblue digital which came up as not pregnant. I'm quite confused as I was under the impression that an evap line has generally no colour to it and both lines are the same colour. Any advise would be much appreciated.
