Are these the sainsburys tests? I've just done one and mine looks looks the same, faint bluey shadow line. My period is supposedly due tomorrow so I would of thought I'd have a clear line now so I'm thinking it's an evap line even tho it came up within the time limit because I've heard so many bad things about sainsburys tests since I bought them. Good luck tho hope it's a positive for us both 🙂 xx
