HI and Welcome
Not being Dr's it's really hard for us to know, but many things can cause it to get worse. If it's allergy induced it could be the time of the year, or maybe if food allergies you are eating something moreso than before or you are ill and your asthma flares. These are all ideas to ask your Dr about because you should be able to maintain your asthma year round
