Burning sensation

So last night I ate a hot pocket n during my sleep my stomach was bugging me n felt like a burning sensation, it didn't hirt t just made me nauseas and I woke up n walked around n it went away, today an about after eating I was laying down n got the same burning sensation in my stomach n this time my throats could this be the start or acid reflux or heart burn ? 😟I'm 20 weeks
