Bubbly urine is not normal and indicates too much protein in your urine which is usually caused by kidney problems.
If your urine continues to be bubbly then it can be a sign of a serious kidney problem and you need to see your doctor to get a urine test done and/or a blood test done as well so they can find out exactly what is wrong as you could have a failing kidney.
When you're kidneys fail you can die without getting on dialysis treatments.
Go see your doctor as soon as possible because something is certainly wrong and you need to get checked out.
