Mucus buildup

Did anyone else experience awful mucus buildup in the first trimester?

I’m 9w 5d and the mucus/phlegm that is just sitting in my chest and making me sick and gag is ridiculous. Once I puke/spit it up I’m fine and have relief in my chest, but it’s short lived as more mucus just builds up.

I know it also may be reflux, but I didn’t experience heartburn/reflux with my son until around the third trimester, so it’s just wild to me to be experiencing this so early.

What did you mamas do for relief?
