Should I call ?

I was originally scheduled for a c-section on the 29th but my doctor said I can move it to the 26th after talking to my husband. That’s what I did, called and scheduled it. I went in yesterday and was tested for covid-19 it’s protocol now (located in VA)

This is my first baby and no one at my doctors office has told me what to expect if I had to stop eating after certain time. Monday they’re closed due to the holiday and I go in Tuesday morning at 6am. Should I call them and ask for information or are they going to call me. (Pretty anxious and want to be prepared)
