evap line? faint positive? or I'm crazy? lol

NOT trying to get pregnant I had the IUd inserted maybe 3 weeks ago and LO is just 3 months old. I've been having those weird vivid dreams and was feeling queasy yesterday so I thought I'd take a test just to make sure the Dr didn't miss something when I got the mirena inserted lol in person my hubby and I see SOMETHING but for the most part it just looks like a negative. I tried to get the best picture possible, please tell me this is a negative and if your eyes see something that it's just an evap line...Also has anyone gotten pregnant on the mirena? I'd love to know to be extra cautious. I dont 
 ant another baby for at least another three years!
