Hi I’ve done a test this morning with fmu ( first morning urine ) and I left it on the windowsill till about a hour ago as I went out and completely forgot! I’ve come back and it has a faint line??? Will attach pics, but then I have done a clear blue (blue dye ) and it’s negative? Am I pregnant ? Am I not?? There’s reviews on the strips saying they give false positives but I done one yesterday night and I just checked again to see if it was negative or positive and it’s still negative but the one from this morning is faint positive? Please help x
