Still so sick

So yesterday I went to a urgent care cause my obgyn office was closed and i have been so sick . They told me I have bronchitis and they called the hospital and talked to the on call obgyn about what to give me . They decided to give me an antibiotic I have never heard of and some steroids and an inhaler and some cough medicine and I also got a shot. Well today I was suppose to start my medicine but I'm scared to cause I have never heard of the antibiotic and the doctor said if I take the inhaler alot it will stunt my babys growth and I dont want that. Then I looked and the cough medicine and it said it has codeine in it . So should I take the medicine or just wait and call my obgyn in the morning to be safe ?
