Don't spend your weekend worrying about it. You have a few days off and worrying about your status on a website means you will turn around on Sunday a nervous wreck waiting on Monday to arrive so you can call at the earliest. Don't put yourself through that.
Monday will roll around, and you'll get your answer then. You obviously didn't "withdraw" before the application, so it's either a mistake in your favor or it means you have been rejected this cycle.
Let Saturday and Sunday be your days of relaxation and catching up on other business. You'll get your answer on Monday, so there's no reason to broach the matter until you call them up. If it's a mistake, then you worried for nothing. If you were rejected, you still worried for nothing.
This country is filled with dental schools, and I'm sure you applied to more than one.
