skiing while pregnant?

My husband works a lot to my best friend was like "I'm sick of California lets go skiing" and I love the idea.
I love skiing and we're both really good at it but I'm not sure if its safe, I'm 13w3d. 
We're skiing since a long time now which means we're really good but I'm scared because of the pressure up there in the mountains or if I should fall, would anything happen to the baby?
