Gurgling stomach?

I have acid reflux (gerd), only started about two weeks ago. But since Friday, my stomach has been very gurgly; I've felt a little nasueous. It helps when I drink milk. But is this a normal part of GERD or should I be concerned? I can't pinpoint it to a certain food either.... I just had bread and milk, which shouldn't upset my stomach, but it's gurgling away and I feel sick....
