Is this an evap line?

[willtheguiltend]

Can anyone tell me is this a positive? or a faulty test or evap line?
Slightly freaking out, I've got the mirena but I've been having period pains and EWCM for the last couple weeks.

I have had a couple like this and not ended up being pregnant, I’d deffo try a different test just incase!

Ahhh okay. That makes me feel a lot better.
