Allergies and asthma while pregnant

Patient: I am currently about six weeks pregnant with my first child. I have had asthma for several years, but my symptoms have worsened over the past week. I have been prescribed Dulera, but I also have an albuterol inhaler anda fluticasone nasal spray. I am very weary of taking all of these medications because there are really no straight answers on whether they’re safe or not. The doctor who prescribed these meds know s I’m pregnant.I guess my question is, are any of these safe to take?

Doctor:
