Super dry cough at night

Has anyone else ever had a bad dry cough at night? It doesn't wake me up. It's when I wake up to go to the bathroom. My chest is super tight and then I start coughing until I bring something up or move the junk around which is usually really thick at night... I am also 5 mths pregnant which could be some of the problem. I also have asthma to. Any suggestions on how to help would be great thanks.
