Can a pregnancy test look different after a few days? I took two different tests a week or so ago and they looked negative. I had what im assuming was my period, started off as brown stringy discharge the first two days then with a day and a half of light bleeding, then stopped. This was light for what it usually is, but still pink blood. Well The tests had been pushed aside and got hidden under my jewelry box, and i just found them and this is what they look like now. Is it possible that it took the test longer to show up, or does this kind of thing normally happen after a test is taken and its been a few days? Kinda freaky.
