Awful blocked sinuses can’t sleep

I’m a little over 34 weeks and the last week or so I’ve felt so run down. My body aches from carrying around this baby(whilst chasing about 3 under 5🙄🤣)

My throat is killing me from snoring every time I sleep. I’m constantly blowing my nose and even *TMI incase you’re eating😂* after I’ve cleared out all the mucus and snot so I can breathe, the other side of my face and nose feel blocked.😭 I can’t clear both sides at once. Any one able to suggest anything that might help?! I’m losing so much rest
