shortness of breath? pregnancy symptom??

Destynee • PCOS • 2 natural born • pregnant with our letrozole baby🤍
So I'm 4 weeks 4 days. Today I've been feeling like every time I breathe in it stings a little and I can't get a full breath. I'm not sick I don't have any other symptoms or anything. My levels are rising so nothing bad is going on with baby. Is everything okay?? Is this a pregnancy symptom?
