Cough and bronchitis while pregnant?

I was very sick with bronchitis or something with my last pregnancy. It got so bad they had to get me an inhaler and send me to a pulmonary specialist as it lingered for soooo long and would not clear up with antibiotics. To help with the cough, my OB told me I could take Dayquil (NO Nyquil though). Also, for the duration of my sickness, I saw my OB who treated me and was then referred to a pulmonary specialist since it had gotten severe. Hope you feel better soon.
