Help!?? Ultrasound

Caroline • 23. vet tech. endometriosis. pcos.
I have a transvaginal ultrasound tomorrow to check the status of my cysts and see how many there are. Only problem is AF came six days late. So tomorrow will be my last day of my period, very light. Will they still be able to do the ultrasound?? I work 50-60 hour weeks so getting an appointment is very hard so I don't want to reschedule.
