3 month old and fever

My 3 month old has a temp of 100.7 taken rectally. Her cheeks are super red and she was fussier than normal this morning. With coronavirus going on I am very paranoid of everything (I don’t think we’ve been exposed)! I don’t see any teeth popping through...Do I call the Dr. or wait a day or so and see what happens? My husband says wait a day since it’s so low grade but I want to call and see!
