TWW (2 Week Wait) and HPT Results

Ok I know this is is probably an annoying post (1 in 3 million), but I'm testing out my trigger shot.  I had a positive - 3 and they slowly faded each day.  Day 5 or 6 I had an almost completely negative result (you can literally barely see the 2nd line).  Then, the next day, yesterday, I had a positive.  Today, the line faded again.  Not as light as it was the other day, but non the less, lighter than it was yesterday.
