Ear infection or teething?

My little girl is 23 weeks old today, EBF. I notice that she plays with her ears while nursing, sometimes swatting at them and sometimes tugging. I’m concerned about an ear infection, but she hasn’t had a fever or acted distressed/in pain. She does have a slight runny nose, clear, and not affecting her nursing. I suspect teething..but should I make an appointment to have her ears checked? I just HATE taking her to the pediatrician unnecessarily during cold/flu/RSV/stomach bug season 😬
