I took this test and I thought I saw a faint line. But, it also had a dye run. I had just recently read about "washing" excess dye and urine stains from tests by adding a few drops of water. I let the test sit for a bit then came back and added the water and it immediately turned the test line very dark. I thought only hcg could cause the dye to stick. I do know that the test is invalid now and do plan on waiting a few days to test again, I just thought this was interesting. Here's hoping in a few days I get a true BFP!!!
