Well, you should have taken a second reading three days later to be sure it had stabilize, but as cream ales are pretty light and you hit the anticipated FG, and that is a fairly typical fermentation time for a beer as light as a cream ale, you're going to be a-okay.
I think people have a tendency to really want to rush everything so as a response on these boards we have a "*whoa* slow the #@&~ down" reflex. Which is never bad advice. But it's far more pertinent to those who rush far heavier beers on far more regular basis.
And if yooper says it's okay, it's okay.
