If the beer has only been fermenting a week, and is at 1.022, you should definitely see more of a drop. I'd check it again in a week.
You probably do not need to ferment for 4 weeks, I bet you're ready to bottle by 3. The only way to know is to check the gravity and taste the sample too. Don't be afraid to take samples!
