Sick. Can't breathe out my nose. Help.

Ma
Help. I'm due in 5wks and obviously in my "uncomfortable no matter what stage". I have had a cold since Christmas Day that I cannot get rid of and not being able to breathe out of my nose on top of not being able to breathe because of baby is killing me. Looking for any home remidies to unclog my nose. I've tried steam/hot shower and that doesn't work. I'm desperate 😭 thanks in advance!
