took a test about a week ago and it showed negative after the recomended 2 mins..my step son walked in the room as i had the test in hand so i quickly shoved it in my drawer out the way and completely forgot about it..anyway cleaned them out today ans it is now sitting as a clear positive..ive no idea how or when it became positive. I guess what im asking is if the positive reaction was delayed or it was just a fluke ?
