Hi,
Did you see any blood? If not I wouldn't worry about it. If so, and it has stopped bleeding, I think she should be ok. I cut my dogs nails a bit too short before, and just applied a stiptic to it and it stops the bleeding. You could call the vet to reassure you if you need that, But if she is not bleeding, I wouldn't worry about it, OK? Calm down and take some deep breaths.

Everything will be ok.
