Bloated or Nausea?

Been having this weird feeling at the top of my tummy (i would think that its the gastric area, as thats the part where doctor will press and tells you youre having gastric) I keep burping but at some point could feel the vomit in my mouth... Anyone experiencing the same? How do i get rid of the feeling? #firstbaby #1stimemom #pregnancy #advicepls #pleasehelp
