Can super high levels of progesterone cause GERD?

I’m only 8 weeks, but for the past month i have experienced a lot of bad stomach pain, burping, gas, thick sour taste in the back of my throat, and EXTREME feeling of fullness. I can eat something so tiny, and feel incredibly full. Its causing me to not be able to eat enough. The pain in my stomach almost feels like hunger pains. It’s constant. It never goes away. It makes it so I don’t know if I’m hungry or if it’s the pain in my stomach. I know I’m not eating enough but I can’t.

I have also been severely nauseas but not able to throw up yet.

I was looking up some info online and it says progesterone can cause acid reflux in the second and third trimester, BUT do you think it’s possible that I may have high levels of progesterone? I’ve had acid reflux in other pregnancies after the second trimester, but THIS is clear pain and what not constant in my stomach and mid back and feeling full. It makes it hard to breathe almost. And Tums does not help at all. What’s your input?

I’m thinking about asking my doc for a referral to a stomach doctor. Has anyone experienced this?
