Third trimester congestion/sinus issues

Ni

Anyone else dealing with congestion issues during third trimester? Literally the week I entered third tri I started having issues.. first my ear got clogged up (never ever had that happen before?!) then shortly after that I started having postnasal drip which has caused a nagging cough and a raspy voice in the morning. I’m not sick at all, it’s literally just the post nasal drip.. ughh.. anyone else dealing with this? What do you do for it?
