I developed a chronic cough while I was pregnant with my son. Being a former asthmatic, even the inhalers weren't helping. My doctor finally prescribed me some antibiotics because we had no where left to turn. The antibiotics cleared whatever it was that was making me cough right up. During the course of the antibiotics, my husband did a thorough check of our basement and found a large patch of mold. He bleached the mold, but I still had the cough until the antibiotics did their job. Good luck!! I know that I was miserable.
