Pregnancy test

Well I had throw away both of my pregnancy tests yesterday. But Monday I took a pregnancy test and it was negative so I throw it away then the next day wen I was looking through the garbage for a menu I look at the pregnancy test and I seen a faint line and I took another one and it did the same thing next day I seen a faint line. But just last week wen I went to the docs it was negative . So what do y'all think ?
