I am almost 32 weeks pregnant. I have had a cold for about a week, but now most of my symptoms are gone except for my cough, but it has gotten much worse. I'm coughing all the time. Sometimes it's hard to even catch my breath. It has caused me to throw up a few times. I've broken down and taken Robitussin, but that hasn't helped much at all. Any advice? I don't even know how I'm going to sleep tonight with this cough.
