Pregnant?

Tameika • Ptegnant with baby #5
Okay so I took a pregnancy test earlier and as it was going across the window the positive line showed up for about 1 minute then slowly started fading away. It just disappeared. This has never happened before. Usually it doesn't show up at all if I'm not pregnant. I'm nit crazy lol I saw that positive line as clear as day. I'm just confused now lol.
