Pregnancy tests arent supposed to tell you how far along you are (unless digital) some women never get dark lines :) if you dont...you shouldnt worry :) Also on strip tests...the test can get overloaded with HCG. At 4 weeks the test line was stronger than it was at 6 weeks :) I suggest diluting your urine a bit and it will come up darker. Also after a while...the HCG starts decreasing Xxx
