Is this real, or do I just really want it to be there?

I took my IUD out on May 5th and have not gotten my period yet. I've had negative tests up to yesterday, but today I think I see something. I've been tracking my bbt, cp & mucous and I do think I know when I ovulated, and a bfp right now would fit. But I still can't tell if there is a line, or if I just really want there to be a line. What do you think?
