Suspected ear infection...doctor??

CC

I think my baby has an ear infection...she’s super clingy and fussy, tilting her head, hates nursing, can barely sleep, crying etc etc. she’s been congested for a week but no fever as far as I know. Should I take her to the doctor or wait it out? She’s 5.5 months

UPDATE we saw dr and ears and lungs are ok, she said just waiting out this cold 😴😰😭
