Query: Overall OK- but one false positive

I like to use these because they are inexpensive and are accurate. This week, though, I did have one false positive, which was very upsetting. I had a very faint line with color, which was similar to the first line I had with my last pregnancy (which ended in miscarriage). I was so excited and tried a few other tests- all negative. I looked online and others have complained of this very thin line being a false positive. It is upsetting to think you are pregnant and then find out you are not!
