is this faulty?

Victoria

just to explain a little. I know I am pregnant however had some bleeding over the weekend and have been doing small strip tests to watch the line until Friday when I have my early scan. I haven't done a test in a couple of day and done one today to find the second line (pregnancy linr) stronger than the other, I've never had this before. is it faulty? I am 6 weeks and 4 days today xx
