I have a cold

I feel like poop. My head feels swollen, my throat is swollen shut and I can't breathe. My doctor told me I had an upper respiratory infection she gave me some antibiotics for a UTI and said it would help with my cold symptoms (I'm 34+5 weeks ) I can't stop coughing which keeps my husband awake and I can't eat anything cause my throat it closed.. what common cold medicine can I take to help??
