Line, line eyes, or indent?

Amber • 7/1/09 miscarriage (8w2d), 5/31/10 my son was born, 5/26/15 chemical, 6/24/15 chemical.
Took this this morning, I'm 13dpo, AF due tomorrow. I see a line, but my temps have been dropping the past three days so I'm not convinced. What do you think? I know it's blue dye, so please don't tell me about that, I already know.
