I have been coughing for about three months now. Negative for strep or bronchitis. So my doctor told me it was prolly due to a combination of GERD (acid reflux) and allergies. I found out I was pregnant a month in to this coughing episode so I stopped taking Zyrtec and Zantac...cough is worse when I eat and when I lay down. Any suggestions bc it won't go away?! I cough throughout the day.
