Curious first time mom

Ailani

My 1 year old have been congestion for a week now. She is recovering from some infection that was going around. She finished antibiotics Her doctor gave her. Now she is just congested , she plays normally and active but sometimes she breathes out her mouth & I put her on the asthma machine all the mucus came out clear. She has allergies but I’m nervous she has asthma. Is nasal congestion linked to asthma ? She sounds stuffy and breathing out her mouth. I need answers
