I did a clear blue test and to start with it didn’t come up with a line or not that I could see. But then shortly after the time window it had the second blue line. I just want to know if what it is? Is it an evap line? Or a positive? I have done research and there is so many mixed opinions on these things especially with clear blue. I am slightly early before my period so will test again in a couple days time I think as I have been getting a lot of symptoms.
