Very common I guess cos I'm experiencing it too. But this is my first time nasal congested, my first 2 pregnancies I didn't have any. Mine started at 17 and ended ard 19w was sneezing or congested from the moment I try to sleep and went thru the night that I even took ART cos I was worried too abt covid.
I guess our hormones play a very big role during our pregnancy. Be ok soon momma! Have a humidifier in the room. Should make u more comfortable.
