line eyes ?

soooo i have a box of the easy@home pregnancy tests and have had a few sharp cramps, lots of gas, bloating and the tiniest bit of brown in my discharge over the past three days (today is 8dpo). I waited the 3 minutes and checked, A clear FAINT POSITIVE!!) then took a second look and it was gone.... anyone every have this before ?!? added photo of the test after the line disappeared (tweaked)
