I haven't had this problem since being pregnant, but last winter I had the most miserable cold ever. i was so congested and my face was swollen. I was told to rub Vicks vapor rub on my feet before bed (and by rub, I mean coat them thickly with the stuff) and wear socks over them so as not to make a mess on the bed. the very next morning, my congestion was completely gone and I felt 90% better. So if it's safe to do during pregnancy, I DEFINITELY recommend that technique. Many many people swear by it (Google it ). GL!
