Took this test today on second day of missed period, The leaflet says "it does not matter if one of the lines is fainter or darker than the other. The appearance of the pregnant result may vary" Can't decide if second line viable enough or not, and I really want to know!!!!!
Lovely BFP. Its not dark but you don't usually get dark lines early. It is clear (no squnting and holding up to the light required) and obviously pink though so it definitely counts as a BFP.
