Doc called saying TO come back

I had a well women's check on the 18th she said blood work can back normal but very low on vitamin D. Then she said doc would like to do a follow up on my pap and she sent me to the schedular who could tell I was nervous and said if it was an emergency the doc would ask me in the same day and wouldn't ask me to schedule. but what do they consider an emergency? stds? pregnancy? HPV? my mind is racing
