Hi, I just did a clear blue pregnancy test, and normally I sit it down and don't look till my timer goes off. Today I watched it after I put it down. I saw the urine come through the test window and make a really strong line that would be an obvious positive, then made a control line, then the test line slowly faded away and was completely gone by the time 3 minutes was up. Is this just normal and the reason you're not supposed to look until the time is up?
