Evap line or positive ?

Has anyone had a positive pregnancy test strip then took another one, and it be negative? I took one last night and I threw it away, and about 10 minutes later, took it out of the trash a looked at it and it was positive. I took more and they were all negative.

Took one half an hour later and it was negative, then took three more when I woke up, all were negative. I’ve never had an Evap line show up on any of my pregnancy tests. Picture below of the positive, to me it looks too dark to be an evap line
