Help! These burps are grossing me out!!

For the past 3 days I have been burping this really foul, nasty odor. I always have stale burps in the morning until I eat something but these are not going away and they are making me sick! They smell and taste so bad and taste like rotten food. YUCK!

What in the world could this be? HELP!

 

You may need a probiotic to add so good bacteria to your stomach. I use good belly but a ffriend uses activia yogurt.
