And if it does help, you should go to your doctor for an asthma workup. A lot of women seem to discover that they have exercise-induced asthma when they start cycling. I have it and am now on daily preventative medication (Accolate), which makes such a difference on cold-weather rides. I breathe much better and cough much less.

Good luck!
