Were you holding the test upside down??? Lol!!! I couldn't resist...But stranger things have happened. However...It would be very odd for two tests to have the results show in the wrong window. I would look at the instructions again to make sure:
a) you were holding the test the right way (usually with results to the right and the end you pee on...On the left).
B) you read and followed the instructions properly (maybe you thought the result window was the control window and the other way around).
It sounds as though you did have a positive result. I would do one of two things...I would either buy a different brand of test to compare results or I would call the manufacturer of the test you took to see what they think.
Hope this helps! Best of luck!
