Maybe Positive?

Hey ladies! I need a second pair of eyes on this one. I'm pretty darn sure there is a line on this test and trying to decide if I should take another in a few days or maybe tomorrow? Took this test last night around 6p. I have no idea what my dpo would be, as I am not actively trying and also on Mirena. This would be a huge shock. I appreciate your help ladies! You make all of this kind of stuff not so scary.

The pic below: top is from 2 days ago. The bottom is from last night.

And adjusted to grayscale.
