Pregnant with the flu

I’m just ranting , I’m 31+ weeks I’m uncomfortable, in constant pain, and now I’ve got the flu! I already had horrible shortness of breath and now being congested makes breathing even more difficult! I was having dinner and almost choked because my nose stuffy so I got to breath through my mouth but trying to chew 😩😩😩 I don’t know what to do! I want to take some medicine but no clue what I can take and my doctors office won’t be open until Tuesday!!
