Performing umrah when entering Makkah Mukarramah after leaving the meeqaat

Q: I intend performing umrah next week Wednesday. I will be staying in Makkah for 5 days i.e. Wednesday to Sunday. I will be returning home on Monday. Am I allowed to visit Madinah just to convey my Salaam to Nabi (sallallahu alaihi wasallam) for just one day (Saturday) and return back to Makkah without donning ihram or performing another umrah again?
