sick at 30 weeks 4 days pregnant

Okay I've felt super bad on Friday, fatigue, felt hot, headache, the whole nine yards. Yesterday I woke up and felt great. Now today I once again have a headache, runny nose, sneezing, fatigue, but it also hurts in my chest and back to breathe. I went to urgent care and they said it was Upper respiratory. They did not check for the flu, bronchitis, or pneumonia. Any advice my OB is closed till Tuesday and even at that they said it'll be Thursday before I get in! I'm miserable and worried I may have pneumonia, mainly because it hurts to breathe. Please don't tell me to see a doctor I already have!
