Good morning, sis! Kailangan mo talaga makipag-consult sa OB mo muna bago gumamit ng kahit anong inhaler, kahit natural-sounding, better safe than sorry sa pregnancy. Maraming moms sa circle ko na-advice ng doctor nila ng safer alternatives like saline sprays or just steam inhalation, so check with yours para sure na okay for baby. Praying your sipon goes away soon!
