I am concerned. I think I need to take another test but every test I have ever taken has always been just one line on the right side, which is negative.
some advice: dark line is the one on the left, correct? the line on the right is just to tell you the test is complete and working, however light or dark that one is won't make any difference.
what kind of pregnancy test is it?? If you know then you can go to the company's web site and get the instructions which should tell you how to read it. Also if you still have the box the instructions should be printed on the side
