Hi. I Have Had A Cough For Over Three Weeks

Hi. I have had a cough for over three weeks now. I was put on the Z-pack to help my symptoms after about 2 weeks but I had a bad reaction so now I am on Amoxicillin. The symptoms went away with the Z-pack but in between the time I was told to stop taking that and I received the Amoxicillin my symptoms came back 10 times worse. Now, the cough is in my chest, I have been coughing up something though I couldn't tell you what it looks like, I just know that it leaves a salty taste in my mouth, I have a headache and a sore throat. Also, I have taken my temperature a lot lately and it normally has stayed in the 97 range but in the past hour and a half, I have taken it several times and it seems to be rising, now up to 99.1. 27 and a half weeks pregnant. I also have Chronic Bronchitis. If this is the bronchitis, will the Amoxi help? What can I do?
