Is this an early sign of pregnancy?

Hannah

For the past week give or take, Ive been having bad acid reflux that’s only gotten worse along with nausea and a change in my appetite. The acid reflux started out only at night and went away when I propped my head up, now it’s all day no matter what I’m doing. I’m 3 ish days away from my next cycle. Is it too early to for it to be a pregnancy symptom?
