I bought a packet of test strips but only the cheap ones and I am due on today but thought i'd check as they were so cheap (£1 for 3) there is a very faint line on the first (the pregnancy indicating line) and so I did the other and there was no line (they both had the line to say they had worked.) Has anyone had this before? My boyfriend thinks that it must be negative, I will buy a proper test if I haven't come on by monday but I was just wondering if this has ever happened to anyone?
