Hunger or burping turns into some form of nausea??!

Hi! Since yesterday(Wednesday) I’ve been having this weird feeling in my mouth. My mouth makes me feel like I’m about to throw up but I don’t. It gets weirder when I would feel hungry or like burping, it would change to me wanting to throw up. I feel normal and I’m eat food and burp like normal but my mouth is the only that’s making me feel like throwing up. Does that make any sense? Im taking Junel fe 1/20 but a month ago I took Larin fe 1/20. I know they are related but im not sure if that’s the reason why im feeling this way. Before starting larin fe, i had a different birth control that would constantly make me throw up between the last week and the placebos.
