Should I call back?

So I just found out that I am pregnant, took 5 tests and all positive. I made an appointment yesterday but they won’t see me until August 13th. I work in a nursing home and care for a resident that has shingles. I forgot to mention that when making the appointment, should I call back and ask to speak to my doctors nurse to see what they want to do? I know that pregnant woman should not be caring for someone with shingles as other pregnant coworkers are not allowed to go into this residents room.
