cold/bronchitis 15weeks- need relief!

i caught a virus last week and it’s now this nasty cough that will. not. stop. i have a humidifier in my bedroom, couch drops actually seem to make it worse, babygirl does NOT like robitussin- i throw it all up 2 min after taking, and i’m at a loss. i can’t sleep because of the coughing and it’s gets so bad it’s made me throw up a few times. i have an appointment with my regular gp this morning hoping she can help. does anyone know anything about the codeine cough syrup doctors can prescribe? is that something that’s even a possibility with me being 15 weeks? i need relief, and sleep! any tips would be greatly appreciated 🙏🏼
