Help, I don't think I should have looked....

I took a test yesterday, I thought it was negative my husband looked at it and he thought he saw a very faint line. Well, I saw it sitting in the trash when I got home this afternoon and I decided to look at it again. There is a line and it looks like some color is there! Do y'all think it's just an Evap?! We have been TTC almost 4 years we have had 1 miscarriage Oct 2015. Any advice. I'm only on cycle day 15.....
