So ... I've stupidly POAS too early. 4 days and 3 days.
4 days early - I thought I saw a hairline BFP. Then decided I was imagining it. Was not FMU. Then I in a panic (as I had a spare) did another. Negative (I thought)
3 days early - think I can see a tiny tiny hairline - only in the right light. If I took a picture and posted it, it would look negative.
But ... on inspecting yesterday's hairline BFP, there is a line. A very very feint line ... but there is one there.
The other two (including today's using FMU) are debatable - I think I can see a tiny bit of pink but I'm not sure if my eyes are playing tricks on me!
So - I remember last time the lines dried darker as the days went on, but I also know you're supposed to ignore the reading after 10 minutes.
So - what are evaporation lines? And could this be what they are? Or do you think they are really early BFP's?
