She'll have tons more of those over the next year or three. Soon her legs will be black and blue too. It's just the nature of the toddler-young elementary kid. I had a period with all three of my kids where their face had so many marks from falling, tables, etc. There's this one age where they just hit everything because they are just the right height-shorter than tables,,but not tall enough to see them.
My toddler fell and hit her head on hard ground twice today. I was a little worried about the one tumble, but as long as they keep on moving and act normal, all is good.
I knew she broke a bone when she didn't want to put weight on it. It's usually obvious when there is a real injury: they don't seem right.
