fever and shivering

So about two weeks ago I had the common cold nothing major just a cough and a cold which got better over a weeks time. 
Now two weeks later I've seemed to have caught another one but this time it's worse. I've been in bed for the last 2 days my body is hot but I'm absolutely freezing to the point I'm shivering and no amount of heating or wrapping up is doing the trick. My entire body hurts I've had a headache for the last two days I've been sick. 
If your in the U.K. your probably aware the docs won't prescribe you with anything when your pregnant well at least not mine. 
Any suggestions on what I can do ?
