A little rough is understandable and the signs of a dirty throttle body. A lot rough could mean bad injectors or bad coolant temp sensor, etc. Let the car run for a little time and see if it gets better as it warms up. If it's sputtering and not drivable, yes call a mechanic. If it gets slightly better and is somewhat drivable then I'd drive it to a mechanic...

Post more information.
