Shortness of breath

Hi soo I’m 32 weeks pregnant with my second and I woke up with shortness of breath and it’s like not stopping… feels like I have trouble breathing… I’m sitting down trying to relax (a little hard to do with a toddler 😅) and it’s not doing anything.. is it normal.. should I be concerned and go get checked or just wait and see if it goes away throughout the day? It sometimes gets a bit better but then starts again… I have been coughing for a while (a cold that won’t go away) sooo could that be related to the shortness of breath?
