Although the power to a bedroom should not be "down stream" from a GFI receptacle, look for one anyway. If not in this bathroom, check any other baths and the garage also. If you find a GFI and it resets but not all outlets work again, you have a wiring issue. IF it won't reset, you may only have a bad GFI. But if you don't find one or it won't reset, then I would say it is time to call a Service Contractor.
