mucous and nausea

Kinda gross and I feel crazy asking this but hoping to find some answers, ever since I got pregnant I've had lots of mucous in my nose when I wake up (I thought I was just getting sick but it's daily for the past 4-5 weeks). I feel like it moves down my nose and just sits in my throats all day long and makes me soooo nauseous like if I go to clear my throats I'll gag and when I eat and stuff I feel like it just sits there all day long. Is this normal and if so, how do you get rid of the snot and mucous without puking and gagging?
