Gallbladder or bile reflux?

Hey, I have and constant nausea for 11 months, did tons of gallbladder tests, h pylori tests, and sadly they said I should be perfectly fine. I throw up mainly in the mornings and its the yellowish green acid that apparently you get from bile reflux. Ive changed my diet A TON. Ive done whole 30 then a diet where I do hardly any carbs at all, even added tons of veggies to try and figure out how to help. Im just starting this discussion so I can figure out which issue it could possibly be. Obviously im not a doctor and know hardly anything about this type of stuff so please someone can help me that would much appreciated!
