A health problem is either an emergency or it is not an emergency. If it's not, you can wait the two weeks.
If it is, you shouldn't be making an appointment anyway, you should be seeking immediate help.
If you think it's an emergency, and a medical professional tells you it'll be X amount of time before you can see a doctor, that means you've been triaged and it may not be as much of an emergency as you think it is.
