Do I need to use FMU?

I got a very faint line at 9dpo with FMU. I am now 11dpo and I really want to test again but I won’t be home till later tonight. Do yall think since I got a VFL 2 days ago, it would show up if I did one tonight? Or should I suck it up and wait till morning so I can take a test with FMU?
