Please see a pulmonologist who can prescribe you medicines after reviewing you.

Hi. I understand your concern s. You will need to undergo a detailed examination and investigation like pulmonary function test which is needed for the diagnosis as well as to assess severity of asthma based on which treatment can be started.a combination inhaler is the best. Consult a pulmonologist for the same at the earliest. As if asthma gets uncontrolled in pregnancy it will cause serious implications. Also keep a regular follow up with your treating pulmonologist.

Generally, inhalers are safe in pregnancy but consult your gynaec to refer to a chest physician
