Adalynn is my 3 month old. She has had dirreha for 5 days now. Should I take her to the emergency room since her dr office is closed today. Or should I just wait to see if it goes away on its own.

Yes, take her to the ER. Dehydration can be deadly to a child this young and diarrhea causes dehydration.

Doesn't your pediatrician have an emergency 24 hour number to contact him/her? As J9 said, go to the ER.

You have already waited. It is time to take action. Get her to a doctor as soon as you can.
