post nasal drip? and acid reflux???

I've been having this problem for over a year now maybe even two but I'm worried now since i'm preggo.

Every morning when I wake up I have mass amounts of mucus in my lungs and stomach, and I can feel the thick mucus stuck behind my nose, above my throat. this causes alot of saliva production because the mucus makes me feel nauseous, and i'm constantly coughing to try and bring it out....which ends in me vomiting it up. This sometimes goes on the entire day, not letting me eat anything.

I also get bouts of intense abdominal cramping and burning, which also sometimes cause vomiting.

Does anyone else have this problem? I feel alone
