Acid reflux and/or extreme hunger?

In my first trimester I was dealing with extreme hunger to the point where if I didn’t eat then I would start gagging and I got hungry really fast but now I am in the second trimester and sometimes I have symptoms like gagging and a slight burning sensation in my midsection and sometimes it’s accompanied by hunger very extreme hunger...so am I experiencing acid reflux and hunger or just hunger that’s like my stomach is eating itself or acid reflux and I just don’t it (bc I’ve never really experienced acid reflux in my life). I don’t really get that burning sensation often and if i do it’s like a few seconds...I had acouple days where I did actually have full on acid reflux (a week ago or soemthing) and I took Zantac and it seemed to get better but I’m confused now lol I hope this makes sense...anyone can offer advice?
