Acid Reflux

I never have heart burn or acid reflux, this weekend my fiancé and I had breakfast at a small town place similar to IHOP, I had one biscuit with white gravy (yummm) and I was suddenly vurping, never happens, then today I had a bowl of oatmeal (with cinnamon) and same thing. Seriously 8dpo should this be happening? Any other ladies having out of normal changes?
