I agree with PT747, the warm salt water works wonders.  I use it myself.

Hi Agathasz,

I would suggest trying a Neti pot with warm salt water.     

Here's a couple of links worth reading:

http://en.wikipedia.org/wiki/Neti_pot

http://en.wikipedia.org/wiki/Nasal_irrigation

It's pretty effective, very safe and inexpensive. 

Hope this helps and good luck with your pregnancy...

I suggest you call and ask your dr. or your pharmacist.  Both would know what is best for you and baby.  Congratulations on your pregnancy and I hope you feel better soon!! Bobbie

Mine always clear up with just the antibiotics.  Never needed a nasal spray.
