vfl after a few hours???

Ok so I know that you're not suppose to read a test after 10 minutes, but this test has a fl after a a couple hours of taking it. I read that as long as the line has color than you have hcg, but if it's gray, it's just the test strip...it looks like it has color to me, and after ALL the tests ibe ever taken, none of them have done this before...So...is this what I think??? Could I be pregnant?!?!
