Worried , is this normal?

Just curious , i had a wierd experience tonight. I felt as if i had to burp and pushed a little and a huge piece of what it felt like to be food came up into my mouth. Of course it grossed me out. But thats never happened to me before. What causes that? Is it normal? My girlfriend says it is! I always have an upset stomach though , and im worried it could be connected. but everyone tells me the stomach is because im making it happen from worrying and worrying and worrying about it.

Just wondering if u guys have had that before. ?

i think it is normal.
everybody have some burp or discomfort sometimes.
maybe it is the results of a movement of stomach or bowel.
