I have found using a neti pot to rinse out nasal area really helps. It is safe to use during pregnancy and you can do it as often as every 2 hours if necessary. It is a bit tricky to get the hang of at first, but after a couple tries it's isn't so bad and it can be really helpful to get some of that gunk out of your sinuses and make it easier to breathe! Hot steamy shower or just turn on the shower and breathe in the steam while sitting in the bathroom. Hot dacaf tea of some sort.......hope you feel well soon!
