Possible sinus infection while pregnant

Danielle

Help! My son and husband may have just had the flu I am feeling fine other than my sinus’. My right side cheek and teeth are bothering me a little puffy and my right nostril clogged. I’ve tried steam showers and hydrating and rest it’s been two days. Does it have to be an infection can it just be bad sinus’ and what if it is an infection how do you treat it I’m 15 weeks pregnant? Thank you
