Open Question: Would you sue over tripping over a phone line at work?

I tripped over a phone line at work at my supervisors desk, I didnt notice the line when I turned to walk away, i'm pregnant and fell left side down hurting my knee, shoulder, and left lower belly. I was taken to the ER where i'm now in a leg brace and a sling for torn ligments in my shoulder, but thank god the baby they said the heart rate was good but that is all they checked. Should I sue the government company I work for, for this? I on the other hand was told I'd not owe any bills towards my injury through workers comp. If i did sue what could i get out of the settlement?
