Common cold is killing me!

So I work with the public and handle money all day long, I've had a runny nose since I found out I was pregnant (I know that's a symptom) but it's gotten worse and turned into a cold, heavy head/headache, can't breathe out of my nose and all I want to do is lay down and not move to get some relief! I've been using Vic's vapor rub since that seems to be our only option and I'm currently closed in my bathroom with the water steaming so I can breathe!! Any help or suggestions? Really need to get feeling better soon!!
