Congested, stuffy nose 2 month old

I’ve been sick the past couple of days. A cold with runny/stuffy nose and super congested. My sweet girl has been fine but today she has had a little bit of a stuffy nose. She’s been breathing out of her mouth. You can hear the stuffiness when she’s breathing through her nose. I know it’s safe to give her the little remedies nasal spray? Have any of you mamas used it? Or went through this with your little babies? Just looking for some advice. Her pediatrician is closed on weekends. No fever and she seems to be as happy as ever but she just sounds a little stuffed up.
