Dollar Tree Pregnancy Test Help :)

I bought the New Choice pregnancy test ...and I've used them before and never had this happen. But when I put the urine in the test there was a bright two pink lines within two minutes and then the positive line began to faint by the time the 5 minutes was up...never had this happen. Did this happen to anyone else? Took 2 test and they both did the same thing ....I have 4 test left but decided to wait to test again :(
