Baby fell and hit her head

My daughter is at the age where she loves to pull up on things and my grandparents have hardwood floors. She was grabbing my phone on the couch but lost her balance and the front of her face/side of head hit the hardwood floor. She cried for a min bht I could tell she was in pain. I know they are tough but should I take her to the Er? What symptoms should I look for? Anyone else had this happen?
