Paracetamol, take the full reccommended dose for adults, don't mince around and take a half dose, and take it as offten as you are allowed (i.e. every 4 hours, no more than 8 tablets in a day) Don't take the ones with added caffeine or decongestant, or lemsip.

You use vick vapo rub to inhale if you have a blocked nose too, but I don't think olbas oil is allowed.

Don't want to worry you but this sounds like what I have had. Obviously at this time of year I couldn't be ill am too busy! Dud paracetamol, gargled with salt water etc but ended up really poorly, felt like I had flu. Trip to the Drs who took one look at the huge glands, ie visible from across the room and my mingling throat and temp etc and now on ten day course of antibiotics. Feeling so much better now they are kicking in.
Rest rest rest. It's awful having a cold when you're pregnant, there's so little you can do. Just curl up in bed, have lots of hot honey and lemon drinks and wait for it to go away. I didn't take paracetamol when I was pregnant because I'm a bit paranoid about that sort of thing (also this but it is medically advised as ok.
