A person is waiting outside a shop in a queue(a very famous shop) get the famous shop to get the world famous sweets. So he says:
1.They shouldn't run out of sweets before I'm up.
2.They shouldn't run out of sweets before it's my turn.
What sounds better option 2 or option 2?
And what about other contexts:
I'm up next.
It's my turn next.
When am I up?(or when are you up?)
When is it my turn?(or when is it your turn?)
It's your turn.
You're up now.
