Relief of a head cold

I have a stuffy nose that is really getting on my nerves. I have tried garggling salt water, taking long steamy showers, eating lots of pineapple and oranges, and using a salt water nasal cleanse - but it is still prevailing. I know that as pregnant ladies we are not supposed to use any medication - even over the counter. Any suggestions on how to bite this thing? I need this thing cleared up so I can breathe and sleep!
