I was due on yesterday so I thought I should probably do a test just incase. The first one I did I thought there was a faint line, so I decided to do 2 more (using the same first morning urine - they are the dipstick kind) I read the results after 5 minutes so I didn't think it could be an evaporation line or that I'd left it too long. However on the other 2 I can't see anything. I've took a picture on my phone of the first, but it's not very good quality.
Does that mean the faint line I can see on the first doesn't mean anything? Surely if I'm using the exact same tests, with the exact same urine, they should all come up with faint lines if the first was a true positive?
