Also there is 3 wires thats is covered and 9 wires that goes into the switch that controls the bath room i guess. So there is 3 black,3 white and 3 copper. The switch is labeled for the black on 1 side and white on the other and the copper in the middle. I will take a pic later
If by chance your old switch had a black and white wire going to it, it may be a switch that is considered being at the end of the run.
This is where the power source is coming in to the light, and the switch is placed after the light at the end.
The black and white wires coming from the switch are then used to break the black "Hot" wire up at the light. If done correctly, the white wire should have had the ends colored black with either a sharpie or some black electrical tape to designate the line as being a switched "HOT".
I am not sure if the current NEC codes allow for this type of wiring anymore, but it was done forever to save both wire and time when installing switches.
Here is an example of what I am talking about:
