Gum Pain From Temporary Crown?

I'm not sure if this is normal. This is my first time getting a crown. it's been four days and my gum is still painful. I looked at it with a dental mirror, and just underneath the Cement, my gum is really red. It hurts even worse when I brush it and it bleeds. So i'm wondering if this will go away or because of my gingivitis it's making it worse then it should be?
