6 days after rhinoplasty, and I'm bleeding out of one nostril in the middle of the night. Is this normal?

So, right after the surgery I experienced quite a lot of bleeding, and I was told to expect that. Nevertheless, 6 days after the surgery, long after the bleeding originally stopped two days afterwords, the blood resurfaced. My bathroom looked like the elevator from the shining. Are these possible answers? I don't think I was blowing my nose, just exhaling through my nostrils, not pinching the nose, and I was laughing hysterically by accident earlier.
