Innavacon pregnancy test HELP

Brittany

so curiosity got the better of my today I’m 8dpo according to my Flo app, I had an innavacon pregnancy test in my draw and just decided to do it knowing it probably wouldn’t show anything.. I done it probably around 12 and nothing came I thought I could see a faint line but I think I was trying to see something that wasn’t there I then checked the test 10 minutes ago and I find this... is it a evap line or did it just take its time to show up ? The line is quite thin I dunno what to think an I don’t wanna get my hopes up..

i have a 17 month old son and chucked his test (first response) in the bin as it was negative and checked a few hours later out of curiosity and it was positive and I now have my boy so I’m really confused.. what are your thoughts
