False positive on first response ??

MH

Hey ladies i took a test 2 days ago and I got a positive result but then I took a test today and it’s negative?? Or maybe there is a faint line ?? Idk it should be getting darker not lighter. Maybe it could be from the fact I’m super dehydrated from being on a boat all day yesterday, I got pretty burnt?? Idk. Has anyone had this happen? My period is still 2 days away.

photos are from this morning. Last one is from 2 days ago.
