Burning sensation ?

Brittany • Expecting our second April 2015 ?
I NEVER get heart burn .. So I'm not sure what it feels like . This morning around 2:30 I woke up to pee & I had the worst burning sensation in my chest , but it burned all te way to the middle of my stomach . It almost felt like I had rubbed icey hot all over my chest / stomach ? Does it sound like heart burn ? Or just a weird pregnancy symptom . Lol
