Evap or vfl?

I am 12dpiui. The top one was taken around 5 am, i didn’t see anything, tossed it and went back to bed. About an hour later I noticed the line. I know it’s invalid since it wasn’t within the time frame. So I took another test 2 hours later and still see a faint line (within the time frame). But it looks grey to me so I think it may be evap. I have never gotten an evap before on these tests, help! 🥺
