Antibiotics

Brittni
So I'm 15 weeks and 3 days pregnant and I've been super sick with some kind of cold, cough and sore throat for about 3 weeks. Tmi but I'm coughing up green stuff and blowing out green and blood and my chest and throat is killing me. I went to the walk in two times and all they gave me was an inhaler. It's been almost a moth and I'm only worse than I was. Has anyone taken antibiotics while pregnant? Are there any safe ones you know of? What would you do if you were me?
