faint line only on angle? am I insane... just evaporated line ?

My period isn't due for 8 days. I had sex day after ovulation on May 26. So I'm not even sure if it's possible to even have a positive yet... when I look at the test there doesn't appear to be anything but as I turned it I noticed a slight line... but could just be the evap line and nothing more. I feel cramps and bsck aches like I do when my period is coming.... but I also felt that way last time before I found out I was pregnant. I had a MC in October and a D&C. Everything month I'm so paranoid I hate it... help
