Passing Stool with an Ostomy - Is This Normal?

I've had an ostomy with a loop since October. Mucus from the rectum is not unusual, but the last couple of days I've been passing some stool. Is this normal?

I've had my ileostomy for two years and once in a blue moon, I will pass a little drop (if it's normal stool then I would check with your doctor) and was told it can happen. Just be aware if there's blood or if it's yellow and smells.
