Just been through my 2nd FET, the first failed. Today is OTD and I tested this morning with their blue dye test and a second line appeared. Never had a positive pregnancy test in my life. Tested again tonight to make sure with a cheap pink dye test and its really faint, the pic makes it look darker for some reason. Now Im worried I made a mistake, I should be 4wk 5days surely the line should be darker.
