Sick when breastfeeding

I have a fever of 101.1 with a terrible sore throat and ear ache. I’m thinking of going to an urgent care bc I feel so bad. My question is tho can they do anything for me since I am breastfeeding?? Are there any antibiotics I can take? My primary care physician is booked and I’m 4months post partum so I don’t think I should go to my OB for sickness.
