Me and my husband have been trying for over a year. I took a test on 3/1 bc I was nauseous and had a faint blue line but chalked it up to an evap bc of the placement. I decided to test a few days later because I couldn’t stop thinking about it and again the same thing. Today, I got the sudden urge to test again and go another thin blue line but this time completely centered. These pictures were all within the 10 minute window. I am super worried that this is just evap lines. Does anyone know what is happening or if these are valid? I really hope they are but I know blue dyes can be unreliable.
