Vvvvfl

I’m not sure what to think. Maybe I’m going crazy but it is the first time ever I think I’m seeing something resembling a very very very faint line. I’m 10dpo, this isn’t FMU as I just randomly decided I wanted to take a test during the day and couldn’t stop myself. Could it be a vvvvfl? Or is it nothing? There is a bit of a glare in the picture btw, looks better in reality, I’m just not that good with taking pictures.
