faint line or evap line?

My period was supposed to start yesterday. My period is like clockwork, always on time. However, i’ve had very light spotting whereas it’s usually incredibly heavy flow on day 1 for me - always.

I took a pregnancy test today but not sure if it is an evap line or a faint line. There is blue colour to it, especially when you look at the test in-person, although on camera it’s hard to see.

Thanks for any help!
