What happens if I start my Fantasy-League after the first LCS games today?

Hey guys I've got a little issue and I am not sure if it's okay or not.

Yesterday when my friends and me wanted to open our fantasy-league the servers were down so we can't do that.

But today, however, we'll see us only after the first LCS games so my question here is: Can I create my league after the first games and if so, will the first points count also for us or not?
