Not a doctor, but I do have asthma, and my symptoms sound very similar to yours. Exercise and cold weather are my main triggers, which makes cycling in winter Not Fun. Wearing a scar/bufff over your mouth might help as that warms the air before it reaches your lungs.
Probably worth going to see your doctor to get a checkup - they'll test your lung function and should be able to tell you whether it's an allergy or asthma or similar.
