I'm terribly late.

I was terribly late.
I was very late.

Are these correct?
If so,which is more natural?:-(
Also, are there any words that is suitable to be put in the place of
"terribly" or "very"?

Thanks a lot in advance.:-)

Both are fine and both seem natural. You could also use really instead.

I hope this helps.
