Is it normal to be short of breath during pregnancy?

Yes, it’s perfectly normal. Shortness of breath can start early in pregnancy , it has to do with how pregnancy hormones affect the lungs. But if you have shortness of breath along with chest pain, a cough, or heart palpitations, if you’re feeling faint, or if there’s a major change in your breathing, then you need to contact your doctor.
