My girlfriend was diagnosed with bronchitis (sort of-long story, ER she went to was sub-par) and was given an albuterol inhalor. A couple weeks later, she found out she was pregnant. She was having some tightness in her chest, and was worried abuot using the inhalor. Is she okay using the inhalor? If not, is there anything that you could recommend us trying to relieve her tightness
